How to make three-dimensional butterfly bookmarks

A square piece of paper.

1, take a square piece of paper, fold the paper in half, and then fold the upper and lower sides to the middle. After unfolding, fold the bottom crease in half to the middle, open it after folding, fold the bottom crease in half and divide the bottom into four parts.

2. Repeat the above operation for the upper part, and divide the paper into eight parts. Repeat the above operations in another direction to form an 8*8 split box.

3. Pick up the paper from the middle layer, there are three layers in the middle, and both sides are positive. Turn to the front, as shown. Unfold the paper and flatten it. The back and front are as shown in the figure.

4. After the paper is unfolded, turn down the first grid, turn to the back, fold the right side to the upper side, press the crease at the upper right Fang Xiaofang block, then fold the two small squares on the right side to the second vertical line, and press the crease at the upper small square.

5. Fold the paper on the left to the second vertical line on the right, and also press out the crease of the small square. Repeat the above folding method for other parts to form creases as shown in the figure.

6. Press the top small triangle inward, stack them all together, and turn down the outermost left and right.

7. Flatten the paper like a book from the front, with five protrusions on the back. From the third page, press the right part, fold it to the right, and the front is four layers.

8. Press down the middle part and find that the upper corner is inclined. Overlap the paper again and fold the lower part of the triangle up a little to make the upper part horizontal.

9. Fold the right angle of the overlapping part upward, fold it along the crease after opening, and repeat the above operation on the other side. Fold and go back to the front.

10, fold the right angle at the top left and right to the middle along the left and right creases, so that the left and right sides are together. Then fold the rightmost lower right corner backwards and the left side backwards.
