i agree with the latest post. If you are copying I would ask permission. Northwest coastal art is designer specific. I took a college class on the subject a couple years ago. Each artist has his or her specific templates. To copy a specific design would be easily recognized.
We used the Bill Holm book as a text. I have attempted to create some designs, but have failed to create something unique that looks halfway different. I do have a cedar bentwood box I carved with a native steelhead template. I would never sell it ( someone elses design) I wish I could remember the book it was in. It was in WCC library in Bellingham.
Good Luck!
