Raw materials: seven pieces of colored paper, scissors and double-sided tape.

1. Fold the colored paper into eight equal parts, then fold it in half, with half glue on the folded part and one glue on the back. Seven copies are folded and pasted like this. Tear off half the glue in the middle and stick it into a small fan. Fold the black cardboard in half. Compare the printing of the small fan, tear off a whole piece of adhesive tape at the back and put it on. Put it on, because you have to put something under your head.

2. When sticking, stick it tightly and open it in one direction, which looks better. You can also decide the direction according to your own preferences. After pasting, take out a small piece of blue cardboard, cut a few big water drops and paste them on both sides for decoration. Cut the green cardboard into grass and stick it on the bottom.
