Indeed very touchy. Spray glue dries too fast in my experience and latches onto the cloth so you can't reposition. Perhaps there is a slow drying stuff. I'm thinking maybe some white Elmer's (not yellow wood glue which dries too fast and is too strong) thinned a bit and painted onto the wooden panel, then the cloth laid on there and stretched and pulled about until in place, and the edges weighted down. Whatever method, the glue has to be slow drying.
