I may be biased but I think most things look better when presented in a teacup. But really, teacup flower pots and planters are among my favorite teacup applications. There's something so whimsical and delightful about growing plants out of dainty vintage cups and intermingling old decor and new life in unexpected ways.
Like with the teacup bird feeders, a great thing about teacup planters is that they are very forgiving of minor imperfections. Say the inside of your teacup is stained, or there's a chip on the rim of the cup that makes it no longer safe to sip; Turning the cup into into a flower pot is a perfect upcycle solution. Besides, the dirt won't be offended and no one has to know.
Creating the planter itself is as straightforward as it gets. Just drill a small hole or two (depending on the size of your cup) through the bottom of the cup to allow water to drain, and you're pretty much good to go. The saucer below it will catch the water (so don't forget to put that underneath your cup before placing it on your table or window sill)! From there, you can add some potting mix and seeds and wait for the magic to happen. Alternately, you can transfer an existing potted plan from its pot and decorate the top with pebbles, gravel or small rocks, and ta-da: sweetest little planter you ever did see. Create a few and you'll have yourself a teacup garden!
A note on drilling: The bottoms of teacups tend to be thin and are therefore pretty easy to drill through using just a hand drill and diamond drill bit. If you'd rather not play with power tools, I'd be happy to drill your cups for you as part of your upcycle order. Just say the words.
