I'm sorry for the silly questions, where I live (N.I.) most suppliers and restorers I have talked to don't know what fresco is and they undertake restoration work. I was curious about the dry wall (plaster board), as most houses (where I live) have stud walls and I was interested to know if fresco can be done on them, considering the books I have read advocate liberal amounts of water, I have a vision of the dry wall falling apart lol.
I do not intend to do any thing over 2' sq as you advised.
