What cartridges can you cut with the Design Studio Trial version?
Depending on where you purchased your Cricut it may have come with different cartridges to what came with someone elses Cricut that they purchased elsewhere.
However, regardless of what cartridges came with YOUR cricut, there seems to be a "standard" cricut package and the carts that came with that package are the only ones that can be used with the DS trial version. They are:
Cricut Personal - George & Basic Shapes (that's one cart - not two).
Cricut Create - Don Juan
Cricut Expressions - Plantin Schoolbook AND Accent Essentials.
