Wire Ornament Hangers Hanger instructions (authors/designers unknown)
I found this info last year while surfing the web. My apologies for not giving credit to the website, but I didn't mark it as a "favorite" and can not find the link.
"To make these pretty ornament hangers, cut a piece of wire about 4 inches long. With needle-nose pliers, curl one end for the part that hooks onto the ornament cap. Bend it into a right angle, then thread on a few beads. Now curl the remaining wire into a spiral that will hook onto the tree or ornament display. Try other shapes and angles and different types of beads."
