I used two 12 x 24 pieces along with one 12 x 12 piece.
How to make mat with paper.
As shown above take a strip end and fold it to make a triangular corner for the mat.
Push the strip end in one of the flaps of the pattern.
After the desired area of the mat is formed the strip ends of the mat need to be tucked in to create a finishing.
A good thing to do to make this placemat last longer as an alternative to contact paper is to laminate it.
You have the option of cutting the freezer paper with the shiny side up or the shiny side down on the mat.
Invert the side of the map and make another triangular fold.
Personally i prefer to work shiny side up i feel like it adheres much better to the cutting mat this way so that means that i need to mirror.
Next cut your freezer paper to size and place it on your cricut mat.
