1. Fold the square colored paper into an X-shaped crease and then into a double triangle, as shown in the figure below.

2. Fold the top right angle parallel to the bottom, as shown in the figure below.

3. Fold the acute angle of 45 on the right in half and overlap with the upper right corner, as shown in the figure below.

4. Then fold the acute angle 45 inward under the triangle formed in Figure 2, thereby locking the acute angle 45.

5. The acute angle of the left side 45 is the same as that of the right side, and the folded effect is shown in the following figure. After this step of bending, it is actually a simple and generous bookmark.

6. Fold the upper right corner in half so that it coincides with the lower right corner. Be careful not to worry, insert it slowly, as shown in the figure below.

7. Finally, the green square becomes a triangle with a hollow center, and the rectangle of 7x 14cm is folded into three parts. The size of the trunk is up to everyone. If you like thick, you can fold it wider, and if you like thin, you can fold it narrower.

8. Fold the triangle in half, draw the level of the tree with strokes, cut it into a hollow shape along the marked part with scissors, fold the trunk in half, and fix it with double-sided tape or white glue at the opening, as shown in the following figure.

9. Insert the trunk into the tree. Just fix the trunk to one side of the tree. Note that the middle of the tree is still hollow. Don't fix both sides!

10, after the trunk is fixed, punch some beautiful dots on the shredded paper to decorate the trunk. Many mothers may not know the name of this tool. Its full name is hand-held single hole punching machine. It is not only round but also heart-shaped. This thing is very cheap, only a few dollars each. If you want to do manual work for your baby often, you can take out one.

1 1, such a simple and beautiful bookmark is completed.
