Purpose
This SOP establishes standardized procedures for cutting fabric to ensure:
- Accurate pattern placement and grain alignment
- Minimal fabric waste and optimal material usage
- Consistent quality across all garment pieces
- Safe operation of cutting equipment
- Prevention of costly cutting errors that cannot be reversed
Cutting is the most critical and irreversible step in garment production. Errors at this stage result in wasted materials (averaging $50-$500 per error), production delays, and potential project cancellation. This SOP ensures cutters work systematically with quality checks at each stage.
Scope
In Scope:
- All fabric cutting for custom costume and garment production
- Cutting of main fabrics, linings, interlinings, and interfacings
- Both manual cutting (scissors, rotary cutters) and machine cutting (straight knife, round knife)
- Cutting for single garments and small production runs (\<50 pieces)
- Specialty fabrics requiring directional cutting (napped fabrics, prints, plaids, stripes)
Out of Scope:
- Leather and synthetic leather cutting (requires specialized SOP)
- Large production runs (>50 pieces) using automated cutting systems
- Sample cutting for draping or mockups (less stringent requirements)
- Trim, ribbon, and notion cutting (covered in finishing procedures)

Step-by-Step Procedure
Step 1: Pre-Cutting Preparation & Fabric Inspection
Objective: Ensure fabric and workspace are ready for accurate cutting.
Actions:
-
Retrieve fabric from storage:
- Verify fabric against design brief: fiber content, color, weight
- Check fabric bolt label for dye lot number
- Document dye lot in production record (critical for future matching)
-
Unroll fabric and inspect full yardage on cutting table:
- Visual inspection: Look for flaws (holes, stains, weave irregularities, color variations)
- Mark any flaws with tailor's chalk on fabric edge (not on usable area)
- Measure actual width at 3 points (beginning, middle, end) - fabric width can vary
- Measure actual yardage received vs. ordered
-
Identify fabric characteristics:
- Grain direction: Pull a single weft thread across width to confirm straight grain
- Nap direction: Brush hand over surface - smooth = with nap, rough = against nap
- Right vs. wrong side: Check for sheen, print clarity, texture differences
- Selvage location: Identify and note condition (tight selvages may require trimming)
-
Relax fabric (CRITICAL for accuracy):
- Allow fabric to rest flat on table for minimum 1 hour (24 hours ideal for knits)
- For wrinkled fabrics: Press with steam iron on appropriate temperature
- For rolled fabrics with creases: Light pressing may be needed
- NEVER cut fabric immediately after unrolling - dimensional changes occur during relaxation
-
Prepare cutting table:
- Clear table of all debris, pins, thread
- Check table surface for snags or rough spots
- Ensure adequate lighting (minimum 500 lux, no shadows)
- Set up pattern weights, chalk, scissors within easy reach
Quality Checkpoint:
- Fabric matches design brief specifications
- Dye lot documented in production record
- All flaws identified and marked
- Actual width and yardage measured and documented
- Grain direction confirmed
- Fabric relaxed (minimum 1 hour)
- Cutting table clean and properly lit
Estimated Time: 30-45 minutes (plus relaxation time)
Responsible Role: Cutter
Step 2: Pattern Layout Planning
Objective: Determine optimal pattern placement to minimize waste while respecting grain requirements.
Actions:
-
Gather all pattern pieces for the garment:
- Lay out all pieces on a separate table
- Count pieces against pattern inventory list
- Identify any missing pieces (notify Pattern Maker immediately if incomplete)
-
Review grainline requirements:
- Straight grain: Arrow on pattern runs parallel to selvage
- Cross grain: Arrow runs perpendicular to selvage (rare, typically for bias bindings)
- Bias: Arrow runs at 45-degree angle to selvage
- Nap layout: All pieces must be oriented in same direction (one-way layout)
-
Calculate fabric requirements:
- Measure longest pattern piece
- Measure widest pattern piece
- Add 2-inch margin on all sides for safety
- Check calculated requirement against fabric yardage available
-
Create layout strategy:
- IF cutting layout diagram provided → Follow diagram exactly (proceed to Step 3)
- IF no diagram provided → Create optimal layout (see Layout Guidelines below)
Layout Guidelines (when creating own layout):
- Start with largest pieces first
- Place pieces "head to head, toe to toe" to minimize waste
- Maintain minimum 1-inch spacing between pieces (cutting tolerance)
- Position flaws outside pattern pieces (refer to flaw marks from Step 1)
- For directional prints/plaids: Align pattern pieces to design repeat
-
Document layout:
- Take photo of final layout before cutting
- Measure total fabric usage (length x width)
- Calculate waste percentage: (Total fabric - Used fabric) / Total fabric × 100
- Upload photo to project folder in Google Drive
Decision Point:
- IF waste percentage >20% → Consult Production Manager for layout approval before cutting
- IF fabric insufficient for pattern → STOP, notify Production Manager and Designer immediately
- IF layout acceptable → Proceed to Step 3
Quality Checkpoint:
- All pattern pieces accounted for
- Grainline requirements identified for each piece
- Layout strategy determined (follow diagram or create custom)
- Fabric yardage sufficient for layout
- Flaws positioned outside pattern pieces
- Layout photo taken and uploaded
- Waste percentage calculated (\<20% or approved if higher)
Estimated Time: 20-40 minutes (depending on complexity)
Responsible Role: Cutter
Step 3: Pattern Placement & Securing
Objective: Position pattern pieces accurately on fabric with correct grain alignment.
Actions:
-
Prepare fabric for layout:
- For single-layer cutting: Spread fabric right-side up, smooth out wrinkles
- For double-layer cutting (most common): Fold fabric lengthwise, right sides together, selvages aligned
- Pin selvages together at 12-inch intervals to prevent shifting
- Ensure both layers are smooth with no bubbles or distortion
-
Position first pattern piece (start with largest):
- Place pattern piece on fabric per layout plan
- Align grainline arrow with selvage:
- Measure from arrow tip to selvage
- Measure from arrow tail to selvage
- Both measurements must be identical (within 1/8 inch tolerance)
- Adjust pattern position until grain is perfect
-
Secure pattern piece:
- Place pattern weights on all four corners
- Add weights in center of large pieces (every 8-10 inches)
- For slippery fabrics: Use pins in seam allowances (never in cutting line)
-
Repeat for all pattern pieces:
- Work systematically from largest to smallest
- Double-check grain alignment for EACH piece
- Maintain minimum 1-inch spacing between pieces
- Position pattern notches away from fabric flaws
-
Final verification walk-around:
- Walk around cutting table, viewing layout from all angles
- Verify no pieces overlapping
- Verify all grainlines parallel to selvage
- Verify adequate spacing for cutting
- Verify nap direction consistent (if applicable)
-
Mark cutting lines (if patterns do not include seam allowances):
- Use tailor's chalk or fabric marking pencil
- Mark along pattern edge, holding pencil at 90-degree angle
- Mark all notches with short perpendicular lines
- Mark darts, pleats, buttonhole placements
Quality Checkpoint:
- Fabric layers aligned and pinned (if double-layer)
- Each pattern piece grain-aligned (measurement verified)
- All pieces weighted or pinned securely
- Minimum 1-inch spacing maintained
- Nap direction consistent (if applicable)
- Final verification walk-around completed
- Cutting lines marked (if needed)
Estimated Time: 30-60 minutes (varies with piece count)
Responsible Role: Cutter
Step 4: Cutting Execution
Objective: Cut fabric pieces accurately and safely.
Actions:
-
Select appropriate cutting tool:
- Fabric shears: Straight edges, lightweight fabrics
- Rotary cutter: Long straight edges, multiple layers, slippery fabrics
- Serrated shears: Prevent fraying on loosely woven fabrics
- Electric knife: Heavy fabrics, multiple layers (requires certification)
-
Cutting technique (for fabric shears - most common):
- Hold shears at 45-degree angle to table
- Use long, smooth strokes (avoid short choppy cuts = jagged edges)
- Keep bottom blade flat against table surface
- NEVER lift fabric while cutting - let fabric remain flat
- Cut in continuous motion without stopping mid-stroke
-
Cutting sequence:
- Start with interior pieces (furthest from fabric edge)
- Work outward toward fabric edges
- Cut large straight edges first, curves and corners last
- Cut outside marked line for seam allowances (if marked)
-
Notch marking:
- Do NOT cut into seam allowance (traditional method - weakens seam)
- Instead: Make 1/8-inch outward snip beyond seam allowance
- Or: Mark notch location with tailor's tack or chalk mark
-
Handle specialty cuts:
- Curves: Use shorter strokes, pivot fabric slightly (not shears)
- Corners: Cut to corner point, pivot, cut next edge
- Internal corners (slits): Cut carefully to marked point, no further
- Bias edges: Handle gently, avoid stretching during cutting
-
Layer control for double-layer cutting:
- Every 3-4 cuts, verify layers have not shifted
- If shifting detected: Re-pin, then continue cutting
- For slippery fabrics: Cut one layer at a time
Quality Checkpoint:
- Appropriate cutting tool selected
- Cutting angle and technique correct
- Long smooth strokes (no jagged edges)
- Fabric remained flat during cutting
- Notches marked correctly (not cut into seam allowance)
- No shifting between layers (if double-layer)
- All pieces cut completely, no partial cuts
Estimated Time: 45-90 minutes (varies with piece count and fabric difficulty)
Responsible Role: Cutter
Step 5: Post-Cutting Quality Verification
Objective: Verify all pieces cut accurately before releasing to sewing team.
Actions:
-
Separate and organize cut pieces:
- Lay out all cut pieces on table
- Group by garment component (bodice pieces together, sleeve pieces together, etc.)
- Keep pattern pieces with corresponding fabric pieces
-
Count and verify completeness:
- Count all cut pieces against pattern inventory list
- IF any pieces missing → Immediately check cutting table for missed pieces
- IF still missing → Alert Production Manager (may require additional fabric)
-
Inspect each cut piece:
- Grain accuracy: Verify grainline markings transferred to fabric (chalk or thread trace)
- Edge quality: Smooth edges, no jagged cuts, no fraying
- Notch accuracy: All notches marked clearly and correctly
- Dimensions: Spot-check 3-4 largest pieces against pattern dimensions (±1/8 inch tolerance)
- Flaws: Verify no fabric flaws within seam allowances
-
Mark pieces for identification:
- Use tailor's tacks or chalk to mark:
- Pattern piece name (e.g., "Front Bodice", "Sleeve")
- Grainline direction (arrow)
- Right vs. wrong side (small chalk mark on wrong side)
- CRITICAL for assembly accuracy
- Use tailor's tacks or chalk to mark:
-
Bundle and label:
- Stack matching pieces together (e.g., both sleeve pieces)
- Pin identification tag to each bundle:
- Project name
- Client name
- Piece names in bundle
- Quantity
- Cutter initials
- Date cut
-
Document completion:
- Update Notion production tracking: Status = "Cut Complete"
- Record actual fabric usage (length and width used)
- Calculate and record waste percentage
- Note any issues or deviations from standard process
- Upload photos of bundled pieces to project folder
Quality Checkpoint:
- All pieces counted and verified complete
- Each piece inspected for grain, edges, notches, dimensions
- No fabric flaws within pieces
- All pieces marked for identification
- Pieces bundled and labeled
- Production tracking updated
- Fabric usage and waste documented
- Photos uploaded
Estimated Time: 20-30 minutes
Responsible Role: Cutter
Step 6: Handoff to Sewing Team
Objective: Transfer cut pieces to sewing team with all necessary information.
Actions:
-
Prepare handoff package:
- Cut fabric bundles (from Step 5)
- Pattern pieces (if sewing team needs for reference)
- Construction notes from Designer (if any)
- Fabric care instructions (for pressing during construction)
-

Exceptions & Edge Cases
Exception 1: Specialty Fabrics (Velvet, Sequins, Lace, Sheer)
When This Occurs: Cutting fabrics requiring special handling techniques.
Modified Procedure:
-
Velvet/Napped Fabrics:
- ALL pieces must be cut in same nap direction (typically nap running down)
- Use pattern weights only (NO pins - leave permanent marks)
- Cut one layer at a time (layers shift easily)
- Use very sharp shears (dull blades crush pile)
-
Sequined/Beaded Fabrics:
- Wear protective gloves (sequins can cut skin)
- Cut from wrong side to protect embellishments
- Use old shears (sequins dull blades quickly)
- Cut conservatively (leave extra seam allowance - can trim later)
-
Lace:
- Consider lace pattern placement for aesthetic effect
- Avoid cutting through prominent motifs (work around design)
- Use sharp shears (lace snags easily)
- Cut one layer at a time for accuracy
-
Sheer Fabrics:
- Pin frequently (every 4-6 inches) to prevent shifting
- Use tissue paper under fabric for better cutting control
- Rotary cutter often works better than shears
Additional Approvals Required: Designer consultation (for aesthetic decisions), Production Manager (for timeline impact)
Exception 2: Fabric Shortage Discovered During Cutting
When This Occurs: Insufficient fabric discovered after cutting has begun.
Modified Procedure:
- STOP cutting immediately
- Document what has been cut vs. what remains to cut
- Measure remaining fabric accurately
- Notify Production Manager and Designer within 15 minutes
- Production Manager evaluates options:
- Option A: Piecing (seaming together smaller sections) - requires Designer approval
- Option B: Order additional fabric (same dye lot if possible) - delays timeline
- Option C: Redesign pattern to use less fabric - requires Designer and client approval
- Option D: Cancel project - last resort
- Await decision before proceeding
- Document decision and rationale in production notes
Additional Approvals Required: Production Manager (immediate), Designer (if design changes), Client (if visible piecing or design changes)
Exception 3: Fabric Flaw Discovered After Cutting
When This Occurs: Flaw not visible during initial inspection becomes apparent after piece is cut.
Modified Procedure:
-
Assess flaw severity:
- Minor (small stain, slight weave irregularity): Determine if flaw will be hidden by seam, lining, or construction details
- Major (hole, large stain, significant structural flaw): Piece cannot be used
-
IF minor flaw and can be hidden:
- Document flaw location with photo
- Mark flaw position on pattern piece
- Continue with piece, noting compensatory construction
-
IF major flaw requiring re-cut:
- Notify Production Manager immediately
- Document flaw with photo
- Set aside flawed piece (do not discard - evidence for fabric supplier claim)
- Check fabric inventory for replacement yardage
- Re-cut piece if fabric available
- IF no fabric available → Follow Exception 2 procedure
-
Document incident:
- Flaw description and photo
- Action taken
- Impact on timeline and budget
- Fabric supplier information for potential claim
Additional Approvals Required: Production Manager (re-cut decision), Designer (if flaw placement affects design), Finance (if fabric claim pursued)
Escalation & Problem Resolution
Common Issues:
| Problem | Likely Cause | Resolution | Escalate To |
|---|---|---|---|
| Pattern pieces don't fit in fabric yardage | Incorrect yardage calculation, fabric width variance, inefficient layout | Optimize layout, consider piecing, order more fabric | Production Manager (immediate), Designer (if design changes needed) |
| Grain alignment impossible | Fabric off-grain from manufacturer, pattern piece design issue | Block fabric to straighten grain, consult Pattern Maker on alternative grain placement | Pattern Maker (grain alternatives), Production Manager (if significant delay) |
| Cutting tools dull or damaged | Equipment wear, improper use, cutting inappropriate materials | Replace blades, sharpen shears, requisition new equipment | Production Manager (equipment requisition) |
| Fabric shifting during cutting | Slippery fabric, inadequate pinning, rushed technique | Re-pin, cut one layer at a time, use tissue paper under fabric | Senior Cutter (technique guidance) |
| Unsure of nap direction | Fabric has subtle or irregular nap | Test fabric in different lighting, consult Designer for aesthetic preference | Designer (aesthetic decision), Production Manager (if timeline impact) |
Escalation Path:
- First Level: Production Manager (all cutting decisions, resource issues)
- Second Level: Designer (design changes, aesthetic decisions)
- Final Level: COO (timeline impact on client commitments, significant budget variances)
