Update on the Toad AA19 , I have now covered the roof with Calico stuck down with 3M Spray Mount.
I have over lapped the sides but kept it flush on the ends. As can be seen from the photos I've added strips of evergreen all the way round underneath.
This adds to the holding down of the Calico and giving it a more prototypical thickness to the edges.
On the top can be seen I've added two thin strips at the ends, this is mainly to stop the ends fraying but I think it doesn't look out of place even though
the prototype doesn't have them, in the photos I have that is.
When I've painted the roof I will then open out the hole for the Chimney, Calico frays easily so this has to done afterwards, I can then supper glue the Chimney in place.
