You can get a collage mat anywhere but my collage mat in the shape of a house is one of a kind! I actually got this idea from a customer that wanted to display photographs from the years her parents had spent in the house. They were getting ready to move and wanted to preserve memories of living there. I thought it was a great idea, too so I am adding the mat to my shop. It measures 16 x 20 so that it will fit into a standard size frame that you provide. My pricing includes the double mat and two pieces of foam core for the backing. You can order any colors you want at no upcharge but if you want to change the design, I charge a $15.00 design fee. Please do not hesitate to contact me with questions.
