Preheat oven to 350 degrees F.

Pinch off a piece of dough (approximately 1 Tablespoon) and roll on a floured surface to form a 3-inch by 1/2-inch log. Shape a finger by pinching one end to form a fingertip and then two knuckles along the log.
Using a toothpick make several lines in the dough along each knuckle.
Insert a toasted almond slice for the fingernail.
