We ordered a Cowboy 538 from Toledo Industrial. It arrived yesterday. As usual, Bob Kovar was wonderful to deal with and we got the machine in less than a week(Toledo to Lubbock, Tx) from the time we ordered it. We bought the machine to primarily sew draperies. However, we are wondering what else this needle feed machine can be used for and what it's capabilities are. Can it sew leather, vinyl, canvas? What thicknesses? What range of needles and thread can it handle? As far as manuals to operate
