Precuts saves me time. I buy layer cakes and jelly rolls to use on my Go not to save money but to have a great selection of fabric color and design all in one package. I would have to spend much more to get 1/4 yard of each fabric design if any shop carried the whole line. I would rather spend a little more and get right to making not prepping. I have less waste with pre cuts. I can cross a jelly roll on a strip die and have oodles of perfectly cut squares with one pass. I have all the strip dies so I can cut all the square sizes I need up to 6 1/2 inches.
