Both of the above methods work well..
If you would like to remove the tent covering at a later date, and be able to replace it...
cover your tent framework with loose saranwrap first (drape it.. don't pull it tight), then apply your Kleenex canvas.. The saranwrap will keep the tissue from glueing itself to the framework.
After the glue dries and hardens, you can take it off to work on the inside of the tent
IF you take it off, do not paint it while it is off, the paint(especially a waterbase paint) will soften the glue..
once everything hardens, and is painted, you can discard the saranwrap....
