How can I use three large bottoms of terracotta pots?

I purchased 3 of those terracotta pot bottoms at Lowes on sale a few years ago. I have not used them because I have not come across ideas for repurposing them. I do have a Front top porch Fairy Garden that I created on a galvanized Tray (long and large) that I purchased and I placed that on top of 3 black milk crates that I put together with long twist ties. I filled up my fairy garden so there is NO ROOM for these three pot bottoms. I thought of making little fairy garden pieces to place on the steps next to the railing but don't want to take up a lot of space on our front steps...ANY ideas, please......thanks in advance.
