Ravelry is making it super easy for designers to donate portions of their pattern sales to aid organizations working in Haiti. You can browse the patterns tagged "Help for Haiti" here. I donated a little bit and bought the "Game Knitting" ebook from Leethal while she was doing her charity shebang this weekend (it's pretty cool, I recommend it... I'd been waffling for a while and it seemed like a good time to give in) but I thought I thought I'd toss a few patterns into the pot so that I can do a little more.
So from now until the end of January, 50% of all Ravelry sales of Dandy, Bad Oyster, and Snowdrift will go to Doctors Without Borders (honestly, the etsy sales probably will too, but just in case I miss one of those...)
