Cutting the Card
Cutting the card is the easy part of this project. But with all the intricate cuts be sure that the card cuts all the way through. I generally cut the project twice by hitting the C button on the machine before unloading the mat. It is frustrating not to have the paper cut properly when you are folding. And the paper tears easily if you tug.
If you are making the card, you need to pick the primary side (for the front) before you start cutting and face that side down on the mat. For the single shamrock you can decide later after you cut, if you want.
I used a font called Maker Penwriting in the SVG file for the card. Jennifer Maker designed it and will give it to you for free. Just search her blog. (The design space file uses an Access font called Alien.)
