A place to send yarn for charity?

So I’m getting ready to move and I have a few skeins of yarn that I bought for projects failed or forgotten about. Not many, maybe 3 or so. I don’t have the labels any more, but I know they are acrylic blends, but not baby soft. Does anyone know of a place I can send it? Throwing it out seems stupidly wasteful.

Local church, senior center or nursing home. Many do crafts/knitting/crochet and appreciate the free supplies.

I saw these places and ideas recently-

Senior citizen centers
Goodwill accepts them I know.

Perfect! Thank you!!
