In 2019, I went to Matale where the 4th Buddhist Council palm scripts are stored. I got a nice demonstration of how they did this and I even have my name written on a palm script from that place. I’m quite sure they sold either pāḷi or English versions of a sutta. I think it was metta sutta. It was a nice demonstration. Getting a palm leaf sutta not only from Sri Lanka, but the Temple where the Palms leaves are stored, would probably be better. They were not so expensive either and came with nice wooden “covers”. I’m not sure why I didn’t remember to send @RobertK to got here, but I think he was short on time.
I think this was it.
