Bill, don't know of any "pc" treatments, but the crocheting cotton is pretty sturdy...doesn't stretch as wool seems to...if I were you, I'd just try it to get the feel of weaving, and the stuff that's available. I've been working up a technique for finishing up the ends of the strap to go around a horn....I separate the ends into two bunches, "whip" close to the separation point, and then again below the horn, forming a hole for the piece (horn or but plug) to stick through, and leaving a kind of tassel below..it looks pretty nifty...I've only done it on a couple of presentation horns..I suspect it isn't very durable for real day-to-day in the woods use...Hank
