DIY Coasters

I really like the agate coasters you can get from catalogs, but I am not at all fond of the prices. Twelve bucks and up for one coaster? Seriously? So as usual, American Science and Surplus came to the rescue. They sell the agate slices for four bucks a piece, and whatever self-adhesive feet your little heart desires for a couple of bucks, and voila! Agate coasters for a third of retail. You're welcome!

Note: I can't believe I need to write this, but according to reviews on other sites, this is apparently a thing some people don't know. Agate does not absorb water. This is because it's made of stone. I'm not sure why this was such a surprise to people, but there you go.
