I used a variation of this pattern for a chapstick holder (which I made a dozen of!): http://www.crochetspot.com/crochet-pattern-chapstick-key-chain-cozy/
Basically I ch 2, did 7sc in first ch. Then in bl only I crocheted sc in each stitch, for 12 rows. Then I chained 10 and ss back into the beginning ch for the key chain loop. Ta dah! A key chain holder that you holds your bubbles so you can have them with you everywhere!
