If you are going to use a fat batting, usually those are polyester and in the end, you really NEED to tie the quilt. Many quilts in the past and currently are tied. My friend just struggled for weeks with a quilt that she made for her daughter and she will tell you how difficult it was to quilt. Took her weeks longer and the binding was so difficult with the thick batting. Keep that in mind to maybe make your binding wider. Good Luck !
