Hopefully, I have just taken the first step from feeling completely helpless regarding Haiti to being helpful. I just contacted CraftHope and am willing to donate an item or two from my Etsy shop for them to sale. ALL of their proceeds (read: ALL = 100%) go directly to Doctors Without Borders.
If you're crafty, join the party and donate something handmade.
If you're a handmade shopper, shop at their Etsy store first.
Update 01.21.10: My two donated items were posted last night around 9pm - and bought before midnight! I didn't raise much in the grand scheme of things, but I did something and it feels good.
