I've made at least 100 pouchs over the years. smaller seems to work best , tend to carry fewer items less weight and only things you'll need. made 200 or so horns. prefer plain and medium size. use cereal boxes for patterns. want a couple patterns? when I use thinner leather such as deer hide I line the pouches with pillow ticking. thinner leather could be a coat from a garage sale. I also like to use old feed sacks or hemp material lined with pillow ticking, I have a pouch made of gunney sack line with canvass for my matchlock , no flap, open top...Regards Chuck Thom
