I've made several quilt's from clothes as well. First I washed everything and I mean everything in the washing machine and threw them in the dryer. The only fabric i didnt use was fabric that i could not iron.Took all the clothes apart and made crazy quilts, and string quilts which I placed as pinwheels. They turned out so well. These clothes all belonged to my dearly departed brother in law. His family loved the quilts. I even used the labels from some of his clothing. Wish I'd taken pictures. Go for it. The skies the limit and you'll get such positive results.
