FAQs

What kind of fabric is best for a DIY mini skirt with a slit?
Lightweight to medium-weight fabrics work best. Denim, cotton twill, linen, or even a stable knit will all hold their shape well. Avoid overly stretchy fabrics as they can be difficult to work with and may not hold the slit's shape.
