Any one can participate in the pillowcase chalenge. The thrust of it is to donate in your own community. They suggest that there are many places these can be donated, nursing homes, chemo clinics, sick, abused, and negelexted children. All the information is available at the American Patchwork and Quilting website. Be sure to visit there to record any that you donate, you don't need a shop to do it.
I got the people I work with at a Hancock Fabrics to make some and our first collection was 62. We will do another collecion in September and hope to at least double that number.
