One of my favorite crafts when I was a kid was making paper chains to count-down the days until Christmas. My kids make Advent trees for that task, so we saved the paper chains for Valentine's Day.
Take both ends of the paper strip and secure (face-up to face-up).
I found the adhesive tabs didn't keep a secure closure, so I ended up stapling the ends to hang the chain in my daughter's room while she was away one Sunday afternoon.
Look for little touches. A little holiday decor can go a long way.
