You can knit up at least four of these in an hour. I've given many as a gift and people love them. They're about four inches around using a size J crochet hook.
Any worsted weight yarn
J hook (5.5 mm)
Large Eye Needle
Round 1: Ch 3 (counts as first DC), 11 DC in 3rd ch from hook. Join with sl st to top of ch 3. (12 DC)
Round 2: Ch 2 (counts as first DC), DC in same stitch, 2 DC in each stitch around. Join with sl st to top of Ch 2. (24 DC)
Round 3: Ch 2 (counts of first DC), DC in same stitch, DC in next stitch, *2 DC in next stitch, DC in next stitch* around. Join with sl st to top of Ch 2. Fasten off and weave in ends.
Easy Peasy! :) Experiment with different yarns! The possibilities are endless!
Here are the four that I just made.
