A rav I know overseas emailed me today that he has a balebos who wants to commission a giant one meter mezuzah to donate and affix to a school front gate (that is 5 meters tall).
He has someone who will make the case but he wants to know if I have someone who can write such a mezuzah.
I did the math and for such a mezuzah I would need a kulmus that is about 65 mm thick. I would write it myself if I knew what I could use to make such a thick kolmus.
Perhaps bamboo? does anyone have any ideas?
