There is still time to enter your one layer Christmas cards in the OLCCC. The OLCCC is always anything one layer Christmas goes with the option to use the twist!
For my card I used the Stampin' Up Peaceful Wishes stamp set. I masked a portion of the card base and stamped the images and then removed the mask and used a T-ruler and black Copic marker to draw the lines to give a layered appearance. I then stamped the sentiment between the lines.
