I so appreciate everyone on this board!!! I have just found the perfect fabric with cars and trucks and construction equipment at Joanns for the back of my grandson's quilt. It was a twill and I was worried about using it on the quilt. I feel so much better now that I have read these comments and am in a happy place now. It will be a while before it is done, still stitching around the appliqué, but will post a picture when finished. Thanks everyone!
