Use cold butter: It's important to use well-chilled butter because this, as well as the chilling time in the freezer, means the cookies won't spread out during cooking which would ruin the shape.
Use parchment paper: This stops the cookies from sticking to the baking sheet.
Freeze the dough: Freeze the cookies before baking to prevent them spreading when baked.
