I have a lot of card stock that I purchased when I got my Cricut. Rather than getting the card blanks I decided to create my greeting cards from scratch using just the card stock and my Cricut.
It was a pretty simple procedure using basic functions of Cricut Design Space. With this process and the stock images on Design Space you can create a simple greeting card in minutes.
Resize the Square
Go to the top bar of the canvas and go to "size." Click the lock icon to unlock the scaling of the square. Feel free to modify the measurements.
Add the Scoring Line
Go back to the "shapes" icon and choose the straight line which is the scoring line and place it in the center of the rectangle to divide it.
