That's a good question! I typically sewed through the rainbow color order once, then cut my square, counted my squares and made another rainbow section, etc. The sections got longer as I went on! I posted a photo of one of my last sections. It should be the last photo now. I did cut my squares 6" so I could use my rotary 6" square as template, and cut around them with a rotary cutter--much faster than drawing around & scissor cutting!
