YouWorkForThem has a wonderful new book on Japanese Traditional Stencil Designs– and not only is it beautiful to look at, the book comes with a CD which contains 100 royalty-free jpeg files of the stenciled patterns for use in your own designs. If you’re looking for interesting art resources to inspire you during the design process, this is the place. Check out their site for many more goodies. The Japanese Patterns No. 1 and the Chiyogami (Japanese wood block printing) collection book both look great.
