Thanks Lynn! I've got four more of the mini character mugs (my mom collected them) and a bunch of Japanese luster ware that I want to use but I'm really hesitant to drill any drainage holes in them. I haven't had the best of luck with terrarium-style (no drainage) succulent plantings. For the Dick Turpin mug I put about a good inch of pumice in the bottom under the potting mix. I'll be keeping an eye on it with a water meter so we'll see what happens.
