These crochet hooks are super easy to use. First, pick the right hook size for your yarn project. If you're a beginner, start with a medium - sized hook. Thread your yarn through the hook and start creating your stitches. The included knitting rings can be used to hold your work in place or to mark a certain point in your pattern. When you're done, just store the hooks in a safe place, like a hook case. Be careful when handling the 9.0mm hook as its color is random. To keep your hooks in good condition, avoid bending them and clean them with a dry cloth if they get dirty.
