DIY Cardboard/cereal Box Bracelets Tutorial from A Fanciful Twist here. Make as plain or as whimsical as you want. I think this would be great for a costume, dress up, etc… The best idea from this project, for me, is using cereal boxes for the base of a bracelet. It’s light, flexible and free. You could wrap anything around it. Cheap, so easy, and creative.
