I got some flags printed out at Publix this morning for cupcakes I am doing next weekend. They are printed as edible images. How long will this sheet keep good? Do I need to go ahead and put these on fondant today, or can I wait a couple days to do that? I was afraid it might get brittle.

you can keep them in a cool place for a few weeks out of sunlight.
I do this all the time

Thanks!
