Ingredients

• 1 1/2 cups powdered sugar
  
• 1 cup soft margarine or butter
  
• 1 1/2 teaspoons vanilla extract
  
• 1 egg, slightly beaten
  
• 2 1/2 cups all-purpose flour
  
• 1 teaspoon baking soda
  
• 1 teaspoon cream of tartar
  
• Decorating stuff

Directions

1. In a large bowl, beat powdered sugar and margarine with an
   electric mixer on medium speed, or mix with a spoon, until smooth.
   
2. Break egg into a small bowl and beat slightly with a fork.
   
3. Add egg to sugar mixture and stir in vanilla extract.
   
4. Stir in flour, baking soda, and cream of tartar.
   
5. For best results, cover the dough and refrigerate for about two
   hours.
   
6. Preheat oven to 375°F.
   
7. Lightly flour counter or use a dough board. Place half of dough on
   surface and form a ball. Rub some flour on the rolling pin and roll
   dough to about 1/8 inch thickness.
   
8. Using a Christmas tree cutter cut out several cookies. Place about
   2 inches apart on an ungreased cookie sheet. If using egg yolk paint,
   decorate before baking.
   
9. Bake 7 to 8 minutes or until lightly brown. Cool completely before
   using frosting or glaze to decorate or it will melt.
