Hi. I've used icing paper a few times before without issue. I have a question regarding how long it could be exposed to air once applied to fondant. I need to do seven 2D characters and have them leaning against the side of a 2 tier cake. I started drawing them all out on fondant with edible ink markers but the tips of all the markers available in my area are too thick so I can't get the details done nicely. I need the images to stand against the cake so I'll need the fondant to solidify. If I roll the fondant, apply the edible image, and dry a few days will the image flake off or will it have melted into the fondant?  I was thinking another solution could be to apply the image to fondant and put it on a sugar cookie or an already dried rolled piece of fondant so I don't need the drying time but I'd like to avoid this. Looking for any experience. Thanks!

I never use edible markers, but small brushes instead and I do make that kind of "plaque"  by cutting out fondant (with lots of Tylose added) and letting it dry for a few days, then paint the image.

Thanks!  I usually paint, as well. This would have been my first time using markers. There are a lot of details in these images so I thought the edible image could help in making them as detailed as possible. 

Update!  I rolled out fondant, stuck icing paper on it, and let dry for 3 days. It worked perfectly :)

c4k3m4k3r - are you talking about icing sheets or wafer paper that you used?
