I have a lot of leather scraps from using leather dies to cut out leather shapes. I want to know the best way to turn those scraps into leather dust for embossing projects. I use a sharp chisel to cut the leather into small pieces about 1/8 inch in size. I used a vita mix mixer and it broke the mixer, then I used a food processor and all that did was make the leather pieces fuzzy. I want to try an electric grain mill next but that can be pricey. Is there a better way to accomplish this task?
