Chris,
There are some very nice horseshoe patterns in the pattern depot but also just do a quick search on the forum. There have been several horseshoe patterns shared in the past.
I am waiting for my rattlebacks to finish carving so did a quick D-Ring snaffle bit pattern while I am sitting here. Those I haven't seen before. I would apply some draft if going smaller than 6 inches or possibly a shallower carve.
