An entry over at WikiHow.com has an article about how to recycle your old socks… Here are a few of the more interesting ones:
Make a drink cozy. This requires a long sock. Cut the whole top of the sock off. It is ready to slide over a bottle to keep the bottle cool (insulated). A shorter sock can be used for cups and cans.
Make garden soap holders. Gardening can be messy and dirty. Pop a soap bar into the bottom of an old sock and tie a knot around the soap part of the sock. Leave the long part of the sock for tying onto a faucet in the garden. It will be ready for you whenever you need to clean up outside after a gardening session.
Make a sock jump rope. All you half to do is tie about 15 or so long socks in a line and you have a neat jump rope! its also fun to use different colored socks!
