I had the same problem with my quilts. When I did my last twin size quilt I tried this method and had no problem what so ever. I had the quilt with me when I went to LQS and they all wanted to know what I did to get every thing so flat and perfect. It's only the second larger size quilt I have done. I was just beaming from cheek to cheek with the compliments.
The method is really easy and I did find it on our very own QB thread. So give it a try next time. I know I'm sticking with it!
Good luck & happy sewing.
