How to fold a wallet with paper?

1. Take a piece of A4 paper, fold it in half along the horizontal axis (as shown in figure 1), and then unfold the paper.

2. Fold the paper from both ends along the horizontal axis direction 1/4 (as shown in Figure 2).

3. Turn it over and fold it in half (as shown in Figure 3), and fold it in half at 1/4 of the longitudinal axis of the paper (as shown in Figure 4).

4. On the back, fold the four corners of the paper at 45 degrees (as shown in Figure 5- Figure 6).

5. Fold one corner of the paper flat by hand (as shown in Figure 7), and fold the other three corners in this way in turn (as shown in Figure 8).

Note that the back can be glued with double-sided tape.

6. The final effect is shown in Figure 9- Figure 10. Can be used to put some cards, change and other functions.
