I made these inexpensive burp cloths by using cute fabric on one side, and white soft fabric on the back. I am sorry I do not know the name of the white fabric, but it was $2.49 a yard at Wal-mart. I like the raw edges look, so they were super easy to sew back to back.
Then I made a few sets of washable nursing pads with the same white fabric.
Here's one of the bibs I made. It also has the raw edges and then velcro on the neck. I just LOVE this Chevron fabric. :)
