Straw.

This is the start of detailing Teignford.
Taking a hank of Plumbers Hemp and chopping it into short lengths produced what you see here.
I did not go too mad with the amount at first- if it went wrong then there would only be a small amount of cleaning up.
However, it seems to look OK- secured with some watered down PVA- not shiny as I had feared.
So-chop some more hemp and fit the water troughs and this scene will be virtually comple.
