Before I learned I could make them, I bought some. But from Sears (2), Linens n Things, and Walmart. You can guess I didn't pay much for them and pretty much got what I paid for. Weirdly enough though, the 2 from Sears wore out in a couple of years (I think the fabric was too thin), and the ones from Walmart and Linens n Things are pretty much going strong if you do not count the abuse (holes) from a puppy and an old and bored (stiff joints, couldn't do much) Doberman.
I haven't gotten to the bed sized quilts though....
