Even if they are not for cake? can I use the cartridges meant for paper for cake? Im in the process of buying a cricut cake and thinking of buying a cartridge to go with it. BTW joanns has a mini for $99 and free shipping. in the coupon code enter EAD331.

You can use any cricut cartridge as far as I know however I don't think all paper ones are useful as the images are too intricate to cut out of edible materials.

You can use intricate shapes with gumpaste if you process it correctly.
