Japanese coasters

When I was in Tokyo a few weeks ago I really had to limit myself when shopping. Not only because of the weakness in the dollar, but also because I didn't really leave extra room in my suitcase. One thing I brought home that I'm in love with is this set of mismatched coasters I bought off a kiosk in the Omotesando Hills Mall. I especially love the pattern with the cat that's holding an orange rat in its mouth! I imagine making coasters like this wouldn't be too difficult, and would make a great DIY Christmas gift.
