Itsy bitsy pieces

I started out with a 2" triangle in a square, I backed it with a matching 2" white fabric. After sewing on all four side I marked it on the diagonal and sliced only the white fabric. SURPRISE. I repeated the process, it is a long process when you have 150+ pieces I increase the size of each added piece by 1" I now added 3" strip of red, score and cut it I am now up to 4" Now to add another color not sure what yet. I am still clipping!
