My daughter is teaching my great granddaughter how to crochet. She needed a little larger crochet hook so it would be easier for Ayana. I used a number 9 mm hook for a pattern and carved one out of cherry wood. A friend had trimmed a cherry tree last spring and I used this wood. The wood is hard but it is mostly straight so it carves fast. The flat spot is important so the hook won't turn in the hand while crocheting.
