Operation Gratitude has a great site, and does some superb work. Right now, there is a push to send hats, scarves and helmet liners to Afghanistan. It's getting cold there already, Kabul tonight is in the 30s. In the mountains, it's going to be colder, and it's only October. The link here will give you patterns and information. There are some more patterns on Ravelry and other sites, I'll put them below.
There are some rules you need to follow, and these are not suggestions, these are mandatory. First - NO acrylic or rayon or other artificial yarns. It must be 100% wool. Acrylic melts when it burns. When it gets wet, it gets cold and nasty. Wool, even when wet, keeps the body warmth in. I'm told that the Cascade 220 superwash is warm, soft and washable. There are other washable wools too. Second - muted colours. tans, browns, Army green, black, deep maroon if you must, dark blue if you want to send to airforce.
Other sites - patterns
USMC helmet liner
Scarves - any pattern you want, plainer the better and long enough to go around the neck once and get tucked in. A Gaiter is great too. You know how miserable it is when your neck gets cold!
Get the needles smoking - let's get these guys something warm, something made with care and gratitude. The address to send to by December 5 is
Operation Gratitude/California Army National Guard
17330 Victory Boulevard
Van Nuys, California 91406
If you want to, you can put in your name and email address, enclose a card, or anything else you think they'd like - the list is on the Operation Gratitude page, but those of us in the milspouse community know what to send, right?
See you at the Yarn Store (if you live in the DC area and want to get together, comment and we'll knit together.)
