How can I preserve this old wallpaper on this crate ?
It is brittle and coming loose at edges. I tried brushing some glue under edges, but it breaks off. If I would varnish over all of it, would the varnish soak in enough to seal it down to the wood underneath? It is so neat, I would like to save it rather than remove it. But I don't want to damage it by experimenting willy nilly. Suggestions from anyone who has done similar?
