I am trying to pre wash and shrink my fabric, its the Legacy studio 100% black cotton from joann fabrics. I realize that it will fade some and shrink some, I wanted to get the most harsh shrink done before I put it on the back of my queen size quilt. Should I wash it and dry on hot? or should I just wash it as instructed on the bolt and dry it on air fluff?
-also when I put it on the back of my quilt, I should do the seams horizontal with a 1/2" seam allowance correct?
