I have purchased some of your tranfer papers and have a few questions. If I don't use all of them is there a certain amount of time that they are only good for? Can they go bad? And what would be the best way to store them? Should they be stored flat in a cool dry area in the packaging they came in or should I put them in a plastic storage container? I just want to make sure they last until I make more shirts, which may not be for awhile. I think the transfers are fantastic and I want to be able to use all of them. Thank you so much for your time.
