Roll the colored cookie dough out until pretty thin (approx 1/8 inch) and then use the small cookie cutters to cut out your desired shapes. Set aside.
Repeat with remaining colors.
Once all of your colored cookie dough is cut out, preheat your oven to 350° F.
Unwrap your half of plain cookie dough and roll out on a lightly floured surface until about 1/2 inch thick.
Arrange your cut out pieces of colored dough onto the rolled out cookie dough how you would like it. You can overlap pieces, as you wish.
Place a large sheet of parchment paper over the cookie dough. Next we will press the cookie dough down- you can do this by either gently using a rolling pin or pressing a cookie sheet down on top of the cookie dough.
The cut outs will distort a little bit more if using a rolling pin.
Remove the parchment paper once the cookie dough is a little less than 1/2 inch thick.
Use a larger cookie cutter to cut your final cookie shape.
Arrange on a parchment lined cookie sheet.
