I cut my own lace starting with a full hide. I use an Australian strander that can be purchased at Tandy leather. Start by trimming the edge of the hide so U have rounded corners and start cutting around the outside. You should be able to cut larger lace this way as long as U have a sharp blade to keep it even. If u want to do more refined work a cutter/beveler would be a good investment. I usually start with a 3/8" string then stretch it and cut the final pass on a string cutter. The last few hide i got were from Tandy when on sale or Sheridan leather.
