Moving steady no breaks. Small sheaths take about 2 hours if I'm using a liner. The 2 pieces of leather have to be cut out to match each other. Then spread contact cement on both sides and cover completely. I use a heat gun to warm the 2 halves but not enough to over heat. This helps the contact cement dry so I can put them together. Then use a roller to smooth. I then trim any extra overlap. Stitch around the perimeter to make sure the 2 halves never seperate. Then measure and cut the welt. Sew the belt loop down. Then cement the welt to the front and back. Then stitch, sand and burnish.
