Got our little photo advent done in time for December. I just get mini-prints of 25 photos from the year, stick colourful scrap paper on the backs, and pin them on a corkboard. Kiddo flips one per day. When it is done, I put the pics in an album (eventually).
No trash, not much effort, fun for everyone, festive even if you do a very half-assed or messy job of it, and encourages me to actually get photos printed like I always intend to 👍
