No, the mix and match is a set as supplied, but it has lots of dies within it that will make great 12in blocks - gives you a lot of versatility. Our quilt group bought a Go, the M&M set, a 2.5in strip die, and a couple of applique dies to give us a selection to start with. Since then, we have added some more appliques - flowers, hearts and Arabesques, because they were on sale.
