I use all sorts of cotton from thrift shops for charity quilts. I can find fabric, 100% cotton scrubs (neat patterns for kids), men's shirts, sheets, and baby sets that are cotton. I even bought a quillow for $2.95 and tore it apart for the cotton. It's amazing what you can find at thrift shops if you look for cotton fabric. About a month ago I even found 6 rolls of new, in the package, twin-sized batting for $3.95 a roll. And I have a lot of fun looking for things I can use!
