The piece of leather is the beginnings of a western saddle, and my first try at carving leather. I was forced to set it down before I roundhouse kicked something! My carving tool arsenal included an awl, several small screwdrivers, various sculpting tools, and a myriad of blunt metal objects I found lying around my home. Needless to say, these didn't work particularly well. I will likely be ordering real carving tools from Tandy *le gasp!*, such as the beveler recommended by Susan Bensema Young in the Guide. It's really hard to get those tiny edges around the leaves pressed down, and then to fade the impressions out nicely.
If anyone has any suggestions and hints, be they carving or knot-tying related, I would be more than happy to hear them!
