Here is a favorite decorative pocket. You can use pre-made bias tape of any size or use your own strip of fabric. No need to cut on bias!
You need a half circle or semi circle and strip of fabric. You can have your students zigzag edge or use pinking shears.
Gather top of pocket.
Place fabric strip and gathered edge of pocket right sides together.
Press seam. Fold fabric over the top, fold over on backside, and pin in place.
Stitch in ditch or top stitch above seam for a decorative look. Fold raw edges around pocket and stitch in place.
