For the book binders among us Boesner carries a great selection of book binding supplies.
For those who were looking müllers ( the flat glass on glass ones) and a morter and pestle among other things, they can also be found atBoesner for good prices.
Also alabaster plaster, high quality chalk for making gesso, all sorts of skin/fish/ and bone glue pellets along with inks and so on... you get the picture.
and finally there is nothing to stop anyone holding a scriptorium at any event ( autocrat dependant of course) The definition of scriptorium is a place to sit down and do scribal minded things hopefully with other scribal minded people. So if this is somehing people like to do then perhaps it might be cool to ask when ever possible that a space be set aside for scribes at events. - just a thought.
