My parents' neighbor has a zebrawood mantle, and still had some cut-off pieces from it from when the house was built about 20 years ago. He offered me a piece the other day, so I now have about a 2' long by 6-8" wide by 3/4" or so (haven't ACTUALLY measured it). This is the first of the pens I'll be making from it, and is a thank-you for him. He actually picked the design. Next time, I'll use calipers (or ANY measuring means) on the beadwork to make the beads more consistent.
