#72 is her first Expression tutorial. After viewing all the Expression videos, you will get real sense of what your machine will do. You won't remember it all, but you will have it in your mind what the capacity of your machine can do. When you NEED to go back and look at how to do something, you won't have to watch a whole hour before finding it....you can just go to this site and choose the function you need.

What carts do you have? I can post some links to things using your carts if you like (not my stuff, but I can search quickly).
Looking forward to hearing what carts you have. I'll subscribe to this thread and keep up with questions. You are going to LOVE your new machine as soon as you get comfortable with it. It just takes a little time.
