Father George Brooks of the
All Saints of America Orthodox Mission [
allsaintsofamerica.com] in DeQueen, Arkansas, makes old-style pine coffins with Orthodox modifications.
The
coffins [
stmarksworkshop.com] come with a three-bar cross and Trisagion Prayer on the outside. Until one is ready to use the coffin for burial, it can also be used to display icons or store books.
Father George also makes other wooden items for home and church use, which are listed on the St. Mark's Workshop
web site [
stmarksworkshop.com].
Shrouds such as the one used for the burial of Archimandrite Joasaph can be purchased on eBay.
Here [
cgi.ebay.com] is a current listing as an example; this particular seller has offered the shrouds in black and in white. I do not know the direct source in Russia.
