Cream the shortening and sugars together.
Beat eggs in one at a time.
Add milk and vanilla.
Combine flour, baking soda, cream of tarter, and salt in a separate bowl.
Mix with creamed mixture into one until well blended. A dough should form.
Cover and chill for at least an hour (preferably overnight.) If you want a drop cookie, just skip this step.
Preheat oven to 350 degrees Fahrenheit.
Separate dough into two balls.
Roll one ball out to about 1/4 inch thickness on parchment paper or a lightly floured surface.
Cut the cookies to desired shapes. Place on ungreased baking sheet.
Decorate cookies with colored sugar, candy, or a simple cinnamon/sugar mix.
Bake for 5-6 minutes or until edges of cookies are golden.
Set out to cool. Once cool you can ice non-decorated cookies.
