Mount canvas to board temporarily?
I live in South America, but I frequently go back to the US, and I want to be able to take paintings on canvas in my luggage. My wish is to take a rolled canvas in a cardboard tube in my luggage.
However, while I am here, I want to frame them. I want to mount them (some are quite large) to MDF panels, but I want it to be temporary. I have tried wrapping the board, and literally taping them as tightly as I can to the back of the MDF. But this is just really unacceptable. The tape is just not holding.
Also, I hate to wrap the canvas around the sharpish edges of the MDF. It just doesn't seem wise.
Please, is there a way to do this? Is there a better way?
