If you still haven't found a calendar for the new year, you might want to check out this accordion calendar from Paper Foldables. When you get to the site, scroll down and you'll see a picture of the accordion on the bottom right. The calendar is free to print. You just have to assemble it yourself. The one in the picture above, I made for my son's room. It was actually pretty easy to put together, just took a little time.
Paper craft tips: One tool I recommend is a bone folder to score all your folds. Another option is using a rolling paper cutter with a scoring blade in replace of the cutting blade. Check to see if you a scoring blade is made for your model. Scoring the folds will make all your folds crisp and prevent any unwanted folds.
Fold up your model and make sure you know exactly how it goes together before gluing. Once you glue, it's hard to take apart. Basic white glue will work but I recommend using an extra strength glue stick.
