fabric.com has a really good selection and good prices. best part, free shipping after $35 so, makes it worth it, 3 yards will give you 108"x108" (they also carry some 110" & 120" fabrics. i have been shopping with them for over 10 years now and have always been happy with my orders. i do piece alot of my backs but when i want a whole cloth i always turn to them first, they even carry 108" wide flannels!
