Thanks.

I haven't done any paper LOs since before I went to Disney a few weeks ago. I really need to get started again!
There are SO many extras! Say you don't want to make a pirate doll, but you can make a treasure chest, map, hat, hook, scull & bones, etc for a pirate LO. Or you want to make an Aladdin/Jasmine LO, but you don't to make a genie doll, you can make a magic lamp or cool palace. I've used the extras to add on to Mickey or Minnie that I made with the Disney carts. For example, I cut a sword for Mickey, and I cut an apron to add on to Minnie for a Chef Mickey LO.
The cheat sheets tell you what's on each cart in a spread sheet form or pdf form, usually. I don't really use them since I like looking through the handbooks anyway. Here's a link with a few cheat sheets for the cart:
