Fabulous for Layered Matting!!!
If you are a scrapper (like me) who loves to mat his/her pics, then this is a must have. I have used up most of the first one I bought and have had to buy a second because I ran out of several of the colors. You can either use it just with a 4x6 picture, or (as I like to do) double mat the pic with a DCWV 4.5x6.5 mat and then use the 5x7 mat. It is a great way to draw attention to one 4x6 pic when you are doing a layout with multiple 4x6s. It also works well with one pic layouts because it make the picture stand out and not get lost in all that space on a 12x12 page.
I would 100% recommend this to anyone who likes to mat their pics (or anything else)!!!
