What's the best way to get small black and white stones for marking Koans?
Local pet store had aquarium stones (really flattened glass beads) in bags for $2.50/color. Each bag had more than enough stones for three Zendo sets!
They also had "premium" aquarium stones for $7/bag - they were a little nicer, but not at triple the cost.
