Speaking of yarn designated for charity I recently found this organization http://www.warmwoolies.org/index.html
called Warm Woolies. Like a lot organizations they want items knitted in wool, what I like about them though is that not only do they donate to China and Russian orphanages but also to Indian Reservations here in the states.
I haven't knitted anything for them yet, as I only discovered them recently, but if you read through the site and click on "thin your stash" they take yarn donations so that people who want o knit for them in the Denver area can get some yarn. They want wool and it also says they take novelty yarn. But it also says no acrylic- isn't novelty yarn usually acrylic??
Anyway Shandeh, this might be a good rout for you to thin out some of this charity yarn. You could e-mail them about acrylic novelty yarn as well.
