There are some books that usually can be found at a local chain bookstore that have patterns for like, $5 to $15. I have a few. All they are, are like black patterns, reminds me of engravings, page after page. There's Chinese and Japanese styles also. You can scan a page, send it to your favorite image editing software and modify them (watercolor them out, make them blue or red or gold (for that fancy maki-e look). Since they are black on white, can import them to Bryce's terrain editor and 3D them with very little modification. These booklets would be in the art section, probably in a stand by themselves.

I personally uses these things when making a box in the maki-e style. (http://en.wikipedia.org/wiki/Maki-e)
