Anh-Minh points us to a great find, these Japanese books called Petit Patterns which include a CD rom with all the patterns in EPS and JPEG format. I did a quick search on Amazon Japan and they have what seems like a whole series of them from flowers, dots and stripes, kids and toys, japanese style, scandinaivian style, and more. Smarts & Crafts also has a post about it and how you can use these patterns for all kinds of craft projects. Doing a quick currency conversion, each book is about $24 USD and I’m not sure about shipping costs. You can also try the Kinokuniya stores in the US. Check it all out! Link.
