Quick question for all of you. I'm about to start my first two sheaths to accompany two knives that I'm finishing up for Christmas presents. The knives are 8 1/2 inches overall length, and I will be making basic pouch sheaths for them. I'm using Silver Creek vegetable tanned tooling leather. I'm looking to buy some Fiebing's Leather Dye, but I'm not quite sure how much will be needed for each sheath. Is 4 ounces enough for one, or do I need more? Thanks for your help!
