If you have a dog who loves to play tug and a pile of old, holey socks lying around the house, then this Instructable is for you! It turns out that you can cut old socks up and turn them into something resembling thick yarn. This yarn — which I refer to as “sarn” (from sock yarn) — can be used to crochet or knit something bulky and durable.
I decided to make some sarn into a monkey tug toy for my dogs because they love playing tug but easily destroy most of the toys we give them. (And what dog doesn't want to beat up a dumb-looking monkey?) The length of the arms and legs of the monkey design are as long as our longest tug rope (about 1.5 meters, or 5 feet, when stretched), so it gives both dogs (and humans) plenty of room to be on any of the tugging ends. It’s held up pretty well against our dogs so far, and is easy to repair.
As a side note, I’ve previously used sarn to crochet a dog sweater. (I got the idea originally from people making yarn from cut-up plastic bags, called “plarn.”) But other than that project and this one, I’ve never seen anybody attempt to make yarn from socks — I’m doing this new Instructable in the hopes that it’ll catch on! It seems to work pretty well as a readily-available, "green," tough, yarn substitute.
