Block Paper Scissors

Learn three pattern hacks for the Dana panties, by Anna Aguirre.

Posted in: Tutorials & Techniques • January 31, 2018






Block Paper Scissors is a monthly column that teaches three pattern hacks. These hacks help you give your Seamwork patterns a custom spin—all you need is paper, a ruler, and a pencil!

This month we walk you through three different pattern hacks for the Dana panties. Learn how to create front contrast panels, a center back lace-up panel, and retro high-waisted bikini-style briefs with a waistband.

Note: For best results, be sure to make any necessary fit adjustments before hacking your pattern.
