Preheat oven to 350 degrees F.
Fit a cookie press or resealable plastic bag with a star template or 3/4-inch star tip. Pipe dough in 2 1/2-inch lines, 2 inches apart on an un-greased cookie sheet. Press a cherry half at the base of each shell. Bake for 12 minutes, until brown on bottom and raw look is gone from tops.
