You can work up beautiful wire crochet pieces with no crochet hook! Use simple barbecue skewers instead!
Use 2 barbecue sticks and rotate them simultaneously for each perfectly round loop and pull the wire snugly. You will get consistently round loops for the crochet look.
You can use these “crocheted” pieces for wire flowers, bezels for stones or beads, and, if you crochet a big enough piece, you can create bracelets.
To crochet wire, use a fine gauge like 28-gauge. Because a wire that fine is pretty soft, you can use either dead soft or half hard.
