You will need a Sharp Crochet Hook to Crochet around the Zipper. The Sharp Crochet Hook works best with sizes 10, 5, and 3 crochet thread, but I used Vanna’s Choice worsted weight yarn (Fern, White, Raspberry). This takes a little getting used to as you will have to pull the yarn tight to crochet with it. Switch to G hook to crochet the rest of the pattern.
