I used a 6.00mm crochet hook for the main part and a 4.50mm hook for the leaf. Worsted weight yarn... Um, and an apple as a test subject.. I was gonna knit it but couldn't find matching DPN's and so crochet was the way to go! I like how it turned out, it is slightly tempting to make one in every size and colour. A red one would be wicked. :)
