The texture is a bit more open than we really wanted but a slurry of lime could be brushed in to the very open areas
clay paint would work very well in this room
The centre of this area is the colour the paint is when mixed and then it dries to a pale ochre.I added yellow ochre to a paint mix of clay and wheat flour paste.
The clay I used is English China Clay from St Austell , kindly given to me by Jo Moore who is the custodian of the China Clay Museum there.
So an Italian house has Cornish clay paint on its walls!!!
