Okay, here's what I've come up with.
I figure I'll sell them individually for $10.00 each. They will be lighter coloured woods, (boxwood, maple, some others for nice grains).
The left pin and the acorn are shapes chosen for their ability to show grains nicely. (Long and sharp or wide and curved.) The castle (okay, rook), just seemed like it fit with kilts. I'll find some bar pins to put on the back.
Opinions?
