Small amount of worsted weight yarn
Size G crochet hook
Take a 2-liter bottle and cut off the bottom (about 2 inches). Use a hole puncher to make holes evenly spaced around the edge. (Mine had 47 holes.)
Round 1: Join yarn with a sc in any hole, and sc in each hole around bottle, joining with a sl st to first sc.
Rounds 2 - 13: Ch 1, sc in first sc and in each sc around, join to first sc.
Round 14: Ch 1, sc in first sc, *ch 1, skip next sc, sc in next sc, repeat from * around, ch 1 and join with slip st to first sc. Finish off and weave in ends.
To make drawstring: Chain 100 and finish off. Weave through chain spaces on round 14. Insert skein of yarn, feeding yarn end through neck of bottle and pull drawstring to close, tying in a bow.
Enjoy, and happy crocheting!
