To answer the questions: Any worsted weight yarn. Any at all. I agree that washable is most logical, but I don't want anyone to have to make any special--and possibly expensive purchases.
I don't have a deadline at present, because I really don't have a sense yet of who all will participate. So if you want to participate, please do. Don't fret about deadlines. I'll keep you all posted as to the progress. If I get too many squares, well, that's the best problem I could hope to have. I'll just make more blankets for the familes of the rescuers.
In a perfect world, I'd love it if people could put a black border (perhaps single crochet?)around their squares, the better to quickly stitch them together with black yarn and have a unified look. If you can't or don't want to, though, no worries. I'll make it work.
You can send the squares to:
Miner Blanket Project
7714 230th Ave NE
Redmond, WA 98053
Any color. Any pattern. Any design. If it's 10 inches in worsted weight, it's perfect. And if you could jot a few words on a piece of paper and pin it to your square, so much the better. You can put your name on it or not, as you choose...but I was thinking how amazing it would feel to receive those blankets and read the loving, caring words of all the people who worked to make it. I would leave the notes pinned to the squares, so the recipients could associate the square with the words.
And I love you people more than I could ever say. I'm off to knit some squares. I'm thinking of a heart pattern I have, in the hopes of putting at least one heart square in every blanket. It seems like all the hearts involved in this--HUGE ones--should be represented.
Did I mention how amazing you are? And did I say thank you?
You are. And thank you again.
