I am working with a Cricut expression 2. When I size my letters, how do I get them to come out the same size when I do my next batch? I go into the menu and select the size icon with abc and the arrows on the left and right. I chose the number 15 for my letter size. After i cut those letters, and choose the next batch, they come out a different size event though the size is set on 15. How to i get around this?
