Ok all, I finished the top. I ended up having JUST enough of the blue (as in only about 10 inches by 15 inches left) whew!.... I still need to quilt it, but that will have to wait a bit 'cause I need to get snapping on my DD's halloween costume.
Thanks bunches to jstitch and Moonpi for their very helpful suggestions! I don't know what I would have done without you.....:)
