I have tons of old clothes in my craftroom. It was packed last year to throw away but then I got lazy. It stayed until now. I research about recycle clothes, google 'recycle t-shirt' and I found it!! Make yarn and knit!!!
Because t-shirt is not soft like wool or any other retail yarn it was quiet hard to knit. I have to tell you when you knit finger will get hurt but also feel great that you make something useful out of junk!!
