Have you seen what is going on over at Craft Hope? Amazing stuff. Crafters can donate items for the Craft Hope Etsy store, anyone can purchase, you can do both if you want to and all proceeds go to Doctors Without Borders. As I type this Craft Hope in two days, has sold well over 300 items and raised $7,000. Go you crafty good things!
There are many other crafters on Etsy doing their bit through their own stores. Just type Haiti in the Etsy search engine and away you go.
There is also a good post over here with links to other places to donate.
