I love the quilting part, but only because I have a longarm. Before that, I disliked sandwiching and quilting. Now the part I like the least is making the back. It seems that I just finish the top and suddenly it occurs to me that the quilt needs a back too. If I have a big piece in my stash that matches really well, I use that, but otherwise I usually try to piece the back from leftover fabric, and that can take as long as making the top.
