I am plotting and planning many a thing for the upcoming Dia de Los Muertos celebration. I'm not Latina (sadly. I think I'd be good at it), but I am pagan and we celebrate our ancestors in much the same way on October 31. I love the colors and celebratory nature of the Dia de Los Muertos festival, and this year I am making a whole mess of projects to celebrate. Tune in next week for a tutorial or two!
There's some great info on Dia de Los Muertos here.
And some great info on the holiday of Samhain here.
