Didn't in the past but I now starch all my fabrics before I cut into them. I realized a wallhanging that I purchased the fabric kit made up of just 2.0 x 6.0 strips for I hadn't starched them for fear they would shrink too much and now all those seams are fraying big time so I put some of my Quilter's Moonshine into my spray bottle and sprayed the heck out of it on the backside, let it dry and then misted with water and pressed it. Now I go ahead and starch all fabrics whether they're in a kit or not so I don't have this issue again.
