Yesterday (and for about a three years before yesterday) I used to have a cabled store-bought sweater hanging in my closet. It was from Old Navy and very pretty but I just didn't wear it anymore. So I tried my hand at recycling.
There's a group on Ravelry called Thrifty Knitters and they have a whole page of tutorials, links and resources on this type of thing. I found one that made it look so easy. The author's "Show that sweater who's boss" was very inspiring.
The above yarn was all reclaimed from the aforementioned sweater. I got about 12.5 ounces of 50% cotton 50% acrylic DK weight yarn. It's white...so now I'm thinking of experimenting with dyeing it myself. There's an article on Knitty on dyeing plant fibers which looks interesting. Kool Aid also seems easy, but I've gotten conflicting reports on using Kool Aid to dye non-animal fibers. So more research is required...
Clearly, another blog post on this topic will be coming :)
