How to add wire to a crochet leaf ============================================ This wire is 80 cm long, with a diameter of about 0.5 cm. It’s coated with a layer of tin foil, so no need to worry about rusting. It’s waterproof and rustproof. For the sunflower leaf, we need about 15 cm. You can cut it slightly longer. If it’s your first time, don’t worry—just leave a little extra length. Then, fold it in half like this. Start the leaf with a chain stitch, then insert the hook into the slip stitch
