Key chains of all sizes are very popular with teens. Teens sometimes express themselves through key chains that they hang on their backpacks or exchange key chains during the very significant time when they receive their driver’s license. You can easily make key chains to give to your friends during Christmas time. The ever popular “boon doggle” key chain is one option (this is where you braid together a durable plastic to make a braided key chain). Use your imagination and create a key chain with a picture of you and your friends. Make a key chain to represent something that is significant of your friendship with the recipient of your gift.
