A caveat regarding this: most pottery that wasn’t made specifically for bonsai tends to lack feet to elevate the pot and leave a gap for drainage. It doesn’t tend to matter when the pot is up on a bench that has gaps between the supporting boards, etc., but it can present a drainage problem for winter storage if you’re not actively thinking about the drainage situation when placing the pot on the ground for winter.I'll throw it out there just because some folks just don't think of it, but thrift stores often have pottery, and hardware stores often have diamond tip hole bits. Got some of my better and more interesting looking pots that way.
