These pieces will be cut up and used "sew-n-flip" on long strips of slightly heavy white fabric and then sewn together to make a large quilt. They'll end up looking kinda stained glass like when finished. Other's will be cut down and made into 4-patches and then into quilts from there. They will all need to be washed regularly as I'm sure they will be used by the families they will be donated too. When we made them in Omaha, they were put to good use. I selected all 100% cotton pieces just like those were. But those shrank quite a bit and I was just trying to prevent that. Must put laundry mesh bag on grocery list...good idea that one.
