Yes, I put outlined items, on wax paper, on a small cookie sheet and then into the freezer. This way is lays flat and undisturbed. When ready, I peel off the wax paper and place onto the cake. I do this for some flowers sometimes too because it's easier for me to handle when they are frozen. Plus, it's easier to place them. I recommend you make a backup piece as well, in case one breaks while you are removing the wax paper. Good luck.
