Wow I love your top it came out beautiful. Try Hobby Lobby if you have one in your area. They have great fleece selections and also offer an online coupon of 40% off about every other week. Also the fleece is at least 60/90 inches wide so that will help with your backing. Or hit some garage sales for a suitable blanket that can be used as backing since your are going to tie it. I know what you mean about $$ quilting can get very expensive.
