Bird feeders are easy to make out of just about anything, but this teacup idea is one of the most fun and whimsical out there. All you need is a teacup, a saucer, some string, and an adhesive. Turn your teacup on its side with the handle facing upwards, then attach it to the saucer with your adhesive of choice. Once it’s dry, attach your string to the handle of the teacup to hang it from a branch. After you fill the cup (and likely some of the saucer, too) up with birdseed, birds can fly up and rest on the rim of the saucer to eat.
