I have the "Round Box" project and want to carve a "bark" pattern on the lid but have no idea how to change the bark pattern from a rectangle/square to a circle. I know it can't be that difficult but I've tried everything. Could someone walk me thru this? I have attached the 2 pieces for you to look at.

Thanks, ChrisRound Box MOM.mpcbark_long_leaf_pine.ptn
