Amen to the freezer paper backing. I've done several quilts requiring autographs, and this works well. Also, at the recommendation of some friends here, I use PENTEL gel fabric pens (Hobby Lobby for sure) and heat set the signatures BEFORE any quilting is done. My advice is to iron the freezer paper only on the places you want signatures and present the quilt top for signatures just like it is. Deal with quilting later!
