After three very wet winters, the outer canvas was in a dreadful state. The fabric needed to be removed. Also, there were signs of inhabitants other than the children.
So, the structure was stripped to the wooden frame.
Then, a new inner cotton layer was draped, the woollen insulation was replaced, and two layers of canvas were wrapped around the whole structure.
How thrilling to see the beautifully restored ‘tent’ emerge.
Thank you JustYurt.
