I have made one coffin together with my friend. He asked me to help him to build a coffin for his baby, and we made the coffin together. It was a long night with more silence than talk, more silent thoughts than words and more sharing than either the silence or words could describe. It was an honour to do it with him, I'm glad that he asked me to help him.
Around here pretty many people build their own coffins or urns. There are courses to teach it, and although it sounds a bit macabre, it makes death feel much lighter, just as a thing that happens to everyone. Although no-one wats to think of it, the death rate is flat 100% within time
I have promised to build the coffins for my parents and the family members who leave before me, and I have wood seasoning in the attic just for it. I don't see that as a death wish or a bad thing. Just as a last service to the ones I love.
Around here there is still a habit that the family members may go to the hospital after someone is deceased, wash him and prepare him for putting to the coffin. I don't know how it sounds to other people, but it really makes it easier to understand what happened - that someone is really away. Most of the time the biggest step in al is to really undesrstand that someone is away.
It seems that I got carried away a bit. The original poster probably won't have much use for the coffin of a 0-year old :?
It's a good idea to build your own coffin, go for it.
