Hi there,
I have attached my two favorite slobber strap patterns; one is for long straps, the other is for short ones. I make mine out of 8-10 oz veg tan leather, single ply, but if you want to double and stitch them I would recommend two layers of 4-5 oz veg tan, or 6-7 veg tan for the outside layer and 3-4 oz chap or upholstery leather for the inside layer. I usually cut veg tan leather out with a heavy duty utility knife--not fancy but it works! Anyway hope this helps, and hopefully the patterns work for you!
