Cricut Expression Cartridges
One of the really cool things about he Cricut Expression is the cartridges. At last count, I think there were 103 to choose from and each one has something worth using. Right now I'm into doing Batman stuff with the kids so my focus has been there, but there is some much great stuff to do with these Cricut Expression cartridges it's nuts. Browse the cartridge selections on the Provocraft site and you'll see what I mean.
Generally, you can cut letter and shape sizes up to 5.5 on the Cricut Machine and 23 inches on the Cricut Expression. The Expression cartridge works with all Cricut die cutting machines. And if you own the Cricut Design Studio, you can preview all the great features.
