Wilton Cookie Cutter

Cookie Cutters..?

My husband's 30th birthday is next week and I want to make him breakfast in bed. I thought about using cookie cutters to cut out hearts and 3 and 0 out of pancakes. I have the Wiltons ABC cutters. Can you use these plastic cutters on the stove? Are plastic cutters sharp enough to cut out shapes on pancakes?
Thanks everyone! I hope my cutters are sharp enough to make the shapes.

I wouldn't use plastic cutters on the stove. Instead make your pancakes and after they are cooked, then use the cookie cutter to cut out your shape. If the cookie cutter is thin and doesn't look like it would go through the pancake without totally flattening it, then trace the shape on a piece of paper, lay the paper on top of the cooked pancake and with a sharp knife, but around the pattern.
