I bought this planter in the local TSC. I noticed it didn't have any drain holes, but I liked it; still do. Anyone have any idea how I can drill drain holes in it w/o the risk of breaking it? I don't know what it's made of; hoping someone sees it, or one of the others TSC sells, & knows. I could put a potted plant in it & pour out the collected water occasionally, but that defeats the purpose of using a planter.
