The method of folding the fan is manual.

Materials required: 3 sheets of A4 paper, wool, double-sided adhesive tape, transparent adhesive tape (or hot melt adhesive) and scissors.

Step 1: Divide the yellow A4 paper vertically in two, and then evenly fold it in half. Everyone should be able to fold this. It doesn't matter if you can't. Sister Shu will give you a video tutorial then.

Step 2: After the two pieces of paper are folded in half, fix them together with double-sided adhesive tape.

Step 3: In order to improve the aesthetics of the paper fan, you can make a small mark on the paper fan in step 2 to separate the front and back. After the second step, turn the crease to the other side, and then stick two pieces of double-sided tape on both ends.

Step 4: Cut out two pieces of wool with a length of about 25cm and stick them in the middle of the double-sided tape shown in Figure 3. Fold the bottom of the fan and fix it with double-sided tape.
