Walmart fabric
I have gotten incredible buys there, as well as just what anyone would expect. I bought a fabric collection from David Textiles on the clearance table for $1/yard, made my Mom's 90th birthday quilt, and it has washed beautifully, even in the nursing home's industrial laundry. I often buy off the clearance table for charity baby quilts and pillow cases. Touch it well, hold it up to the light to judge how thin it is, and be thrilled when you get a bargain.
