I cut the W&N to about 10" larger each way than I need it when I am ready for it and then I shrink it. I have a front loader and I just use the water temp the finished quilt will be washed at and run it through the rinse cycle. I then dry it in the dryer, fluffing it frequently. It always comes out nice and I don't have the extra shrinking (as long as everyone follows the directions for washing.
