I worked for one of the Washington State University Cooperative Extension offices before my retirement, and our volunteers had great success teaching young girls and boys how to make a pillow case. They loved the bright color combinations used for the border and trim that were found in the donated fabric stashes. They were also taught how to make simple shorts with elastic waistband and a simple vest.
This has been a successful outreach in the community for over ten years. Good luck and bless you for promoting sewing in the youth of America!
