For anyone one a budget but wanting to use a clicker press this is the one that I use. https://amzn.to/43GTfJW If money was no object then I would be getting this one https://www.buckleguy.com/bg-manual-clicker-press-w-swing-head-black-4-ton/ I do not have any affiliation with buckleguy, they just make really good stuff. unfortunately I haven't been able to get any discounts for you guys for them either.
This is a free (or for donation) CAD program that is specifically for Leathercraft. I have been using it for a couple of weeks and it is truly amazing. https://coffee-craft.net/en/leathercraft_cad
My makers mark stamp just arrived!! It looks so great. I am very happy with it. I need to practice on some scrap to see how various amounts of casing will make for different quality stamping.
