Take a tac and tie the string in a knot around it. Do the same to the side. Now stick the tacs into the wall at a distance that you like. Gather your cards and begin pinning them onto the string. Use all sorts of different pins. I had some cute paperclips and bows that were attached to bobby pins. Use whatever! I only made one row for now to display some of my favorite cards, but feel free to make as many rows as you like. I think this is a great way to display your favorite cards from the people you love. It'll make you smile thinking about the day you received them!
