Dave,
I think your price guess is a good one, but your idea with this wood art is "GREAT". I get pretty bored seeing word art without imagination. It does not take much to make a word art pattern and cut it. It is nothing like creating a portrait pattern. I believe a person new to scrolling can learn to make a word art sign in 20 minutes, but giving it character, like you have done, makes the word art a pleasure to look at. One can make 15 word art patterns in a half day, but that is what they are, 'words'. I know people like their names in wood but coming up with something interesting and new is where 'art' comes in. Nice piece, good luck on your sales.
