Have a Cricut? Baby Bug, Create, Expression? Even Cricut Cake? If you do, then you need Design Studio. Design Studio, or DS, lets you weld shapes to create your own designs, you can weld letters together to create words. However, the best feature I have found on it is that you can accurately measure what you need so that you're not cutting several times just to get the right size. This wastes both blade and cardstock, no?
Design Studio eliminates that. You can measure the area you need the title, then create your title in DS so that it fits that space. SO easy! Also if you are creating a layered character, you can lay all the pieces out on the mat, cut your cardstock accordingly, and cut all the pieces out in one fell cut.
Personally, I cannot seem to operate my Cricut anymore without Design Studio.
