Wattle and daub

This was often the infill, the bit that filled in between the timbers.

Wattle was the hazel twigs that were woven together to make a frame.
Daub was a mixture of things, often 80% clay, 10% straw or horse hair, and 10% cow or horse muck (to help it all stick together).
The daub was pressed on by hand to build up a layer.
This was then covered with a lime plaster.
The lime plaster was often coloured.
