In clearing out my drawers of all the old "been there/done that" tees I have I decided to knit a rug with them. Have just finished turning them into my "yarn" and am looking forward to knitting a bath mat out of them or maybe, to preserve them a little longer since the rug will be, in fact, a little memory rug of crap I've done over the years, I'll use it in my room so I won't have to step out onto a cold floor of a morning.
I think rugs are a cool way to use up some stash yarn. Although allowing people to trample on them is a little depressing. HA!
