Input
- Materials
- 6 cm fabric base with an internal 4 cm guide mark
Activity
Despite initial optimism using paper stiffening for exact base cuts, full assembly revealed critical friction: needle resistance strained execution and direct 4 cm cutting left insufficient seam margin, causing severe edge fraying. To resolve structural breakdown during stitching, we transitioned to a 6 cm fabric base with an internal 4 cm guide mark. Overlapping these wider margins before stitching ensures sufficient anchor space, preventing fraying while preserving exact 4 cm visible grid lines.
Outcome
Wider overlapping margins stopped the fraying while keeping exact 4 cm visible grid lines.

Learnings
Paper stiffening made the needle work hard, and 4 cm cuts left too little seam margin. A 6 cm base with a 4 cm guide mark fixed both.
