Go check out this awesome post by Ruth. (Okay, looks like I can't link a specific post. So just go to the blog. It's probably the first one.) She blogs at knittingbloggyblog. She knits for charity (also for herself and kids sometimes).
I have been watching her knit mittens, socks, sweaters, hats, etc. for this orphanage for the last few months, although it feels like years b/c when I found her blog I read through all her archives.
It is really neat to see pictures and hear the stories of the kids actually getting the knitted stuff. Like, when you put it in a box and send it somewhere someone who actually needs it and appreciates it is going to get it. Too cool.
I don't do any charity knitting. But I am thinking about it. Imagine knitting for someone who really would love to have something nice and warm to keep you snuggled in when the temps hit 40 degrees below 0 in the winter. It's inspiring.
