You don't need to drill a hole or stick tack to the walls to mount a holiday card display. You could opt for a tabletop display, such as the Scorpion Large Tri Fold Silver Christmas Tree Card Holder or the Carriage House Creek Scalloped Edge Card Stand. Alternatively, you could keep your cards together in a decorative box such as the Rifle Paper Co. Large Embroidered Keepsake Box. These low-profile designs are easy to pack up and put away at the end of the festive season.
