Cheap wine glass + tea light candle + paper cup with bottom cut out:) THAT'S REALLY SMART! Would be cute for a wedding/baby shower or dinner table decoration! You could use the battery operated tea lights instead!
Cheap glasses, rubber bands, and frost spray paint. Place rubber bands how you want, then use Rust-Oleum Frosted Glass spray paint, waiting 2 min in between coats. Once dry you will want to use a sealer to make it water resistant. You can use Krylon Matte
