Now, I've always saved my yoplait lids.
BUT I have not. ever. sent. them. in.
I actually have an envelope full of them, that I thought I would save up and send from last November, but it turns out, they don't take old ones. I thought they were all the same, but a quick google search says I am WRONG. Basically, only the lids from this period are acceptable, and if they have large tears they won't count. Another very interesting thing I learned is that there are teams (((TEAMS!! YAY!))) for collecting these, and there's probably one in your area. My University actually sponsors a drop box for the lids, which actually makes me much more likely to take them in, because for some reason, eating yogurt is way more fun on campus. I know that many colleges, (as well as cancer hospitals, grocery stores, and dental offices) have one of these boxes.
And because my friend is going through chemotherapy treatments, I wanted to do something special for her as well, even though it's a different type of cancer. I made several of these "warms" to keep her cozy in those otherwise dreary hospital rooms.
Coming soon:my first tutorial, if blogger doesn't eat my photos!
