The green lines on the Stepper Card Mechanism Template are for placement. These placement guides help get both sides of the Stepper Card lined up and even.
The blue lines are scoring lines. The red line is a cutting line.
The score line for the Center Step has been removed. That is because this score line will change as the size of the card changes. This score line will be determined and folded by hand when the card itself is being folded.
This template allows me to make any size stepper card I need. The difference between this template and the other Stepper Card Templates, this is only the mechanism. Once the card paper is folded, the card will have to be cut to size. It means doing the process backwards, but backwards is what gets it done.
