I was making some leggings (pins) with a cuff today and took a few photos along the way in case you wanted to try it too!
1. Fold your pattern piece so the hem cut length is a size shorter than normal. In my case, my pattern piece is size 5, so I folded the pattern piece under to cut the cuff at the size 4 length.
5. OPTION 2: Draw a line approximately 1/2″ (1.25cm) from the edge of the cuff and align with leggings hem.
6. OPTION 2: Stitch cuff to leggings along marked line and optionally overlock the edge (excuse my dodgy stitching I was too lazy to put my stretch needle in)! Use some dabs of Sewline glue or pin the trim to the wrong side of the fabric.
9. Finish leggings according to the pattern and try on your little customer!
