At Christmas time I like to switch out the pictures in my frames for more "Christmasy" ones along with red mats. I keep the christmas photos and mats stored in the picture frames all year long then just rotate them to the front at Christmas time, then rotate back to the regular pictures once Christmas is done. Same frames and same hanging arrangement so that makes it very easy!
These ones are my favorite! The bottom picture is of the LDS temple in Salt Lake City, we go there every Christmas time to see their beautiful light display - it's gorgeous!
You can find the Christmas Subway Art Printable from this website. I like that it has blue in it that ties in with my secretary desk. The snowflake is one of my ornaments that I took a picture of, I played around with it using some picture editing software and then printed it out at Costco.
