I just bought an embroidery sampler pattern in aid of the victims of hurricane Katrina. It's only US$10 and it's such a pretty design -- the purchase price goes to the Red Cross. Check it out if you like to stitch and you'd like to help.
Thanks to Sharon B who has listed a whole lot of fundraising efforts, from knitting to quilts, in her blog.
Fellow jazz fan, Bitch PhD, also has some links for donations and notes that Fats Domino is currently listed among the missing in New Orleans.
