Designers on Ravelry, a huge knitting community, decided that they want to contribute to disaster relief organizations to help Haiti with their patterns.
Casey, one of the responsible people on Ravelry, created a special pattern search tab "Help for Haiti"
If a designer wishes to contribute all or part of the proceeds for one of their designs to the Haiti relief effort, they add that tag to the pattern page on Ravelry, then write in the description the details of their donation (what percentage, where they are sending the money). If a Ravelry user simply types "Help for Haiti" in the pattern search box then all those patterns come up, and the knitter or crocheter can help by buying one or more of the tagged patterns. With more than half a million registered users, this can make a serious dent in the money needed to help.
I will donate 50 % of the proceeds of all my pattern sales to World Vision and
Doctors Without Borders on Ravelry, my etsy shop or if you buy through my blog link.
