OK, I did not get arrested. Actually there was such a severe thunderstorm going on, all the associates were hauling buckets and mops to catch leaks from the roof. Anyway, I pulled a few threads loose from the end, lit them with the lighter, got a hard residue, figured it was poly blended. Did this with four of the prints I liked. Then went to the regular rack and got some nice stuff, VIP and Cranston for $2 a yard. I guess it doesn't say much for WalMart security, but I do have guardian angels that keep me out of trouble. Bottom line is, it's a great buy for clothing construction, but not a great deal for quilting.
