Suggested Fabrics and Materials
This block is designed for woven fabrics. Suggested options include linen, cotton, viscose, chambray, poplin, lightweight denim and satin.
Your fabric choice will affect the silhouette: softer fabrics create a more fluid shape, while fabrics with more body emphasise the curved barrel leg.
- Main fabric: approximately 1.5–2 metres, depending on size and fabric width. Check the fabric guidance and your cutting layout before purchasing.
- Waistband elastic: choose a width compatible with the waistband casing and adjust the length to fit.
- Matching sewing thread.
Not designed for knitted or stretch fabrics. Recalculate fabric requirements if you change the length, width or design.
Printing and Projection
- Print at 100% / Actual Size. Do not select “Fit to Page”.
- Measure the test square before printing the complete pattern.
- After editing, check that the pattern scale and print layout remain correct.
- For copy shop printing, request A0 output at 100% scale.
- Calibrate your projector and check the scale before tracing or cutting.
