i have just one little trick that works for me...i have just one little machine. My Kenmore. i love it. it's just a simple machine. so i keep my quilting simple. people are going to use my quilts. (not for show or art purposes.) Well, here's my tip....i lay my batting out and smooth and flat. usually on the spare bed. and i do that for a couple of days before i layer quilt. and it really seems to help with the wrinkles and bumps. it gives the batting time to relax. then i just layer and pin and quilt.
