How to make a box pleat

Mark, fold, pin, press.
Step by step
- On the wrong side, mark fold lines dotted and the placement line solid.
- Hand-baste along the lines so they show on the right side.
- On the right side, match each fold line to the placement line.
- Pin plenty, then press, removing pins except one at each end.
- Hem before pressing pleats. Topstitch or edgestitch to hold the form if you like.
