I live in Plano too! Small world. Project Linus has several drop-off locations in Plano. They take donated fabric and cut it up to put together simple quilt kits. I picked up two of them a few weeks ago at the Plano Quilt Show. Just need to finish up the binding on them. They provide quilts to Parkland, Samaritan Inn, and several other great charities in Collin and Dallas County. Since I'm trying to practice my skills on my new Longarm machine, these small quilts are perfect for me. Some of the other charities that collect quilts have lots of rules about exact size of quilts, type of fabrics, etc. Project Linus seems to fit me a little bit better.
The Plano Quilt Guild would probably love to have a sale of all of her old templates, tools, etc and be able to use the money for some of their charities.
Hope you find a great place to donate all of that fabric!
