Several years ago when I belonged to a Guild, we made Aprons to wear during our Quilt Show, so everyone would know we were Guild members while we worked the Show. Everyone made the same pattern from unbleached muslin. The Bib of the Apron was a 12 inch square, and we each got to make our own Quilt Block, using whatever fabrics and colors we wanted to for our Bib. They turned out great, and we got lots of nice comments from people who came to our Show.
