Start by using masking tape to tape off the top and bottom, then sponge paint the middle with glitter (or otherwise) fabric paint. Then either freehand, or with a template inside the candle holder, doodle a pattern with a like-color metallic paint over the top of the sponge painting, carefully remove the masking tape and let dry. Add a tea-light or votive and let it cheer up your space!
We did this for Valentine's Day, but it would also be lovely at Fall - with gold, or Christmas... feel free to play with colors!
