Print the wedding advice cards on white cardstock using Cricut Design Space. This will print a box around them and they will print four to a page. The box is for your Cricut to see the edges and know where to cut.
After the Cricut has finished cutting, you will want to turn your mat OVER in order to remove the cards. This will prevent them from curling. Peel the mat back from the material with it upside down.
Repeat the above steps for as many cards as you think you will need at your wedding.
