Al used the following
Craftool Stamps Craftool Stamps: to create this design: B198, B936, F898, F900, F976, H907, P234, P368, S632, S705, S706, S932, U853 and V462. After the tooling was completed, Al removed the background areas (called filigree) and glued a piece of suede behind the tooling. To filigree the design, he used a craft knife and round drive punches. It's pretty intricate work. Of course, you don't have to do the filigree work to create this pattern. Just use Craftool stamps A104-2 and A104 to background the filigree areas.
