For Checkerboard Cookies: Roll out each portion of dough between waxed or parchment paper into a 1/2-inch-thick rectangle. Refrigerate dough on a flat surface for 30 minutes or so to make cutting easier. Cut each rectangle horizontally into 1/2-inch-wide strips. Lay 5 strips of alternating color on a piece of waxed or parchment paper, making sure they touch each other. Then over the first layer, place a second layer of strips, alternating the colors, and then a third layer on top of this, alternating the colors (you can add a fourth layer, if you like). Wrap in plastic wrap and refrigerate 2 to 3 hours. Heat oven to 350 degrees. Slice into 1/4-inch cookies and place on a parchment-lined baking sheet pan and bake 10-15 minutes.

Slice into 1/4-inch cookies and place on a parchment-lined baking sheet pan and bake 10-15 minutes.

For Wheel Cookies: On waxed or parchment paper, roll light or dark dough into a 1-inch-thick cylinder. Roll out contrasting-colored dough 1/4-inch thick.

Slice into 1/4-inch cookies and place on a parchment-lined baking sheet pan and bake 10-15 minutes.

For Square Cookies: Roll out each portion of dough between waxed or parchment paper into a 3/4-inch-thick rectangle. Refrigerate dough on a flat surface for 30 minutes or so to make cutting easier. From each rectangle, horizontally cut 2 strips 3/4-inch-wide. Place a light and dark strip next to each other. Lightly brush with egg white and and place remaining 2 strips in reverse order on top. If desired, reserve some dough (either color) and roll 1/4-inch thick and wrap around the length of the square, giving it a border. Wrap in plastic wrap and refrigerate 2 to 3 hours. Heat oven to 350 degrees. Slice into 1/4-inch cookies and place on a parchment-lined baking sheet pan and bake 10-15 minutes.
