I'd rather it shrink before I make the quilt than after I have made it. My Springtime quilt was made from jelly rolls and boy did it shrink when I washed it. I had made it to fit my queen sized bed with about 2 or 3 inches of overhang and now there is no overhang. So the Jelly rolls I just got will be washed in the sink so they'll shrink now instead of later.
