I read a suggestion from another quilt I know about steam pressing the fullness out right on the frame. I've had to do that on a few of mine when my border and even a block or two came out with way too much fabric. Steaming helped quite a bit, enough that I was able to quilt with no problems. I'm now in the market looking for a hand held hopefully cordless steamer to keep in my quilting room. I hate lugging my iron in every time I need to steam out fullness. I don't wash my fabrics before I make my tops so I know I will have some shrinking which is good news for me in this case.
