So I saw this story last year but forgot to share it. I'm sorry if this doesn't count since it's not a chairty group but an idea for random act of kindness.
A local group of knitters made hats and scarfs and left them around town with tags attached people could pick them up and get free knitted items. Story here: http://www.zanesvilletimesrecorder.com/article/20121123/NEWS01/311230017/Knitters-bomb-Zanesville-creations
I was thinking how great it would be for crafsters to "Knit Bomb" (or crochet or sew) their area and someone finding a nice handmade item.
