Here's a fun and simple project if you feel like wearing your love of knitting on your sleeve...err...neck.
You will need a metal pendant piece (I don't know the technical term), yarn, glue, and cardboard.
Start by cutting the cardboard slightly smaller than the size of your pendant. Cover one side with glue and start wrapping the yarn around.
Alternate the direction you wrap to make a woven pattern. Cover all edges of the cardboard.
Now fill your pendant with glue and press the yarn piece into it. Hold or clamp until it dries a little.
Done! Looking good, you beautiful yarn crafter, you.
