How easy are the Disney cricut cartriges to use?

I have a cricut machine. I have been looking at the Disney Friends cartridge. I know that you have to layer the pieces to get the look that you see on the box, etc. How easy is it to do this? Is it worth the investment? Thanks!|||It isn't that it is hard, but very time consuming. You would have to cut it out of at least 4 or 5 different colors and then piece it together. I suggest using tweezers. Did you know they came out with a Winnie the Pooh and two Disney princess cartridges.
