And, here's also a tip on the wafer paper. People comment on the edges curling. While I was flooding the cookie I smeared (with a basting brush) a mixture of icing and corn syrup on a piece of wax paper and put the wafer image in it to "soak" (careful not to get it on the front.) I didn't have any trouble at all with curling edges.
How did you transfer the "prepped" wafer paper from the "coated" wax paper to the cookie?
