This is a super quick and easy crochet pattern for a cute bracelet.
Yarn: About a metre or two of any embroidery thread
Needles: 4.5mm / US 7 crochet hook and large eyed needle.
Extras: One cute button, crimp bead (optional) and pliers (optional).
Using a large eyed needle, thread the button onto your embroidery thread about 20'' away from the end (see picture).
Make a slip knot about 3'' from the end of the thread, and chain until you're bracelet is as long as you want it to be (i.e. so it's quite tight round your wrist, but fits over your hand). You'll work past the button as you chain, this can be a bit tricky, but just try to keep your loops tight!
When the chain is as long as required, with one loop on the hook, push the hook through the first loop in your chain. Bring the yarn over the hook and pull it through the two loops already on the hook. Cut the yarn and pull the end through the loop. Tie the ends together and trim excess thread. I used a silver crimp bead (these are available in most craft shops) to cover up the knot.
