Mark the swatch before cutting
Put a removable arrow on the reverse. Rotate a second cutting beside the first under the same fixed light. If the appearance changes on rotation, use the approved orientation to mark the seat, arms and back on the pattern.
Recheck yield with the mill and cutter
Ask for the usable width and have the cutter run the one-way layout before ordering. Keep both the approved cutting and the layout drawing. If the buyer sends cuttings for comparative lab work, agree the conditioning protocol with the lab. ISO 139 defines standard atmospheres for conditioning and testing textiles.
Before you approve
ISO 139 specifies textile conditioning and testing atmospheres.
A directional cutting layout can change fabric consumption. How much depends on the pattern pieces and usable width.
Ask for the cutter’s revised yield and retain the signed directional cutting with the purchase specification.
