After fussy cutting or creating a card element with your Cricut, flatten your cut-out by passing thru your die cutting machine. Before, I used paper to protect the element from plate markings. Now, I use a Mylar sheet folded in half. Game changer. It truly protects your project from ANY indentations or markings from the plates. PLUS, it is completely reusable. I bought the Mylar on Amazon which I also use to create my own stencils.
The haunted house in the background was created with the Cricut and the Witch I fussy cut. I followed this tip with both elements with great results!
