Noah, find a smooth bottomed weight to hold you piece still while you tool it. For practice, Tandy sells remnants in a bag that have LOTS of good pieces (even ones you can hand cut more key fobs with. The raising is actually from holding your swivel knife on an angle then tooling with the beveler which lifts the cuts. If you look into modling tools on the Tandy website you can manipulate the cased leather a little.
And btw, yours turned out far better than mine. Keep up the good work.
