If one wasn't particularly interested in seeing the back of the ticket, would it be a mistake to insert a piece of colored paper into the sleeve so that you could double up on tickets per slot (look at one from the front and one from the back)? I guess I'm wondering whether in a cool, non-humid environment; would there be a risk of the color from the paper leaching onto the tickets over a long period of time?
The only reason I mention colored paper is that frequently the border of a ticket is white, so it would be easier to differentiate the ticket from the background with one that was colored.
