I haven't made any sort of final plans for myself. I have decided against cremation, though, and I would like to write my own obit at some point. I know I will not have any kind of embalming or cosmetic stuff done because my family is Jewish.
As for my parents, they both died long ago. My sisters and I worked on their headstones, and on our uncle's, and I can honestly say that those 3 headstones are some of the most original and exquisite I've ever seen.
