Al Sienkiewicz painted it by hand on his canoe as shown on the cover of the Wooden Canoe Issue number 128 from April, 2005 and described in his article on page 14. I have sent him a copy of your inquiry so he may respond directly. Full size patterns for designs like these usually don't work well since each canoe typically has a unique combination of compound curves. Let us know what you decide to do.
