In separate bowl combine flour, corn starch, baking powder & salt
Stir part by part into butter mixture.
Separate mixture into 4-5 separate bowls and add 1-2 drops of food coloring (each bowl gets different Color) into each bowl. May need to add more flour to thicken after food coloring.
Take a little batter out of each bowl and roll out each segment
Once rolled to log form attach each piece end to end.
Now twirl them in a circular motion and place on parchment.
