This bowl was designed using 3Design and WTP. Two 4x8x8 inch blanks were made using walnut, maple, zebra wood, bloodwood, chakte-kok. From the blank 1/8 blanks were cut. Using the OP/ID information rings were marked for cutting on a jig saw. I could get from 1 to 3 rings per blank. The rings were glued rotating about 1/8" each time , keying on the two maple stips next to the center walnut strip.
