How to make a desk calendar?

First, take a rectangular cardboard (preferably two layers), divide it into three equal parts, and draw it on the cardboard with a pencil and ruler.

Second, gently draw pencil lines with a knife. Here, be careful not to use too much force, just scratch it

Third, fold according to the scratch, because the cardboard is two-layered, so it will be very brittle. It doesn't matter if it's not double-decker. Just fold it according to the scratch.

Fourth, cut the edges of the cardboard flat with scissors, and poke holes at both ends of the cardboard equally to keep it horizontal.

Fifth, break the paper clip. It would be better if you were a thin wire.

Sixth, thread the metal wire through the two holes, tighten it on the back, and keep the front fit.

Seventh, stick the post-it note on the front with adhesive tape, so that it is convenient to stick the post-it note and not easy to drop it.
