No moolah left over for real holiday decorations? Give your family’s cheesy greeting cards a purpose other than mailbox clutter. Lining up cards on a mantle is for noobs. Instead, create a gallery wall by hanging a set of matching clipboards in a row. Then clip up and swap out cards as you get them in the mail. Keep the cool ones. Toss the ugly ones. Then use your clipboards to hang non-holiday postcards, artwork, and unreachable resolutions when the new year starts.
