To make the loop use a 20cm length of wire and something cylindrical to wrap the wire around such as a small brad or finishing nail. I used an ink cartridge from a disposable ball point pen. Note: the wire in this photo is oversized to make it easier to see in the photograph. Wrap the wire around the cylinder to form a loop: read more
