I have learned more on this subject with tonight's reading than I have in my whole life. That being said, my father in law passed and we buried him in a " cheap" casket, as life insurance was minimal. I have felt guilty for years about this, the funeral director informing us that it will not stay tightly closed. I feel better now and am glad we made that choice of inexpensive casket at that time. Thank you for sharing your wealth of knowledge.
