You'll need the following supplies (cutting mat not shown):
I took my frame apart and removed the mat. I rolled out my marble contact paper, placed my mat on top of the back of it, and cut out a piece with my utility knife. I eyeballed the amount of paper I needed but if you'd like to cut a perfect section, you might need a ruler.
I removed the contact paper backing and pressed my mat in place.
Note: the inner edge of one side of my mat was straight while the other was beveled (shown above). I pressed the straight side down onto the back of the contact paper to ensure a straight line when it was creased.
I cut the excess contact paper off along these lines:
I folded it each flap backwards and pressed it in place on the beveled side of the mat:
I popped the mat back in the frame, added some art, and hung the frame up!
I love how chic the marble looks against the thick black frame I chose!
Covering the mat in marble paper (or any other paper!) is a great way to update old mats that aren't your style or that may have yellowed over time!
How would you upgrade an old photo mat?
