- What went in
- A 6-centimetre fabric base with an internal 4-centimetre guide mark.
We were initially optimistic about using paper stiffening for exact base cuts, but full assembly showed serious friction. Needle resistance made stitching difficult. Direct 4-centimetre cuts left too little seam margin and caused severe edge fraying.
To stop the structure from breaking down during stitching, we moved to a 6-centimetre fabric base with an internal 4-centimetre guide mark. Overlapping these wider margins before stitching ensures enough anchor space. It prevents fraying and keeps the exact 4-centimetre grid lines visible.
Wider overlapping margins stopped the fraying while keeping exact 4 cm visible grid lines.
(We observed it)
Paper stiffening made the needle work hard, and 4-centimetre cuts left too little seam margin. A 6-centimetre base with a 4-centimetre guide mark fixed both.
