These are some of my "cheater" cookies: I didn't make the cookies themselves. They're good old Lorna Doone shortbread cookies from the grocery store. I piped a white border, flooded with white, and then just "glued" on the wafers with corn syrup. I tried a few with a black border, a dotted border, etc., but I liked the plain unbordered ones best. A lot of bang for the buck in terms of time spent decorating.
