I don't have any of Anna Griffin's new cartridges, but they will work in any Cricut machine. All of the cartridges, except some of the ones for the Imagine, do. She also said that on HSN. If you have an original Cricut, the small one, then you might have some difficulty getting the card bases to cut large enough for a standard card. When I used my small Cricut, I would cut the base by hand and use the cartridges for the embellishments.
I have one of her Christmas cartridges. While the designs are beautiful, there are a lot of layers. You don't have to cut them all; but if you want to, it takes a lot of time. There are no directions in the booklet that comes with the cartridge, and the booklet is a bit difficult to follow. I do love the results, but it isn't an easy cartridge to use.
I hope this has helped you.
