1. Fold the two diagonal lines of the square colored paper into X folds.
2. Fold the origami horizontally into 4 equal parts, compact the crease and unfold it.
3. Then fold the origami lengthwise into 4 equal parts.
4. Diagonal lines of two small squares in the second row are folded outward in two directions respectively.
5. When the diagonal crease is folded downwards, the top edge is also folded downwards, forming an isosceles trapezoid.
6. Fold the lower origami into an isosceles trapezoid shape.
7. At this time, there are four small squares in the middle of the origami. We will fold the right angle of the small square in the lower right corner to the center point.
8. After folding, fold down the small triangle above the clip in the figure.
9. The small square in the upper right corner is also folded in the same way, so that the fish's tail is formed.
10. Pull down the 45 sharp corner on the left and flatten the diagonal crease of the small square in the lower left corner.
1 1, turn the other 45 angle upward, flatten the diagonal crease of the small square in the upper left corner, and form a vertical isosceles trapezoid on the left side of the origami.
12. Fold the upper and lower right angles on the left to the center point respectively, so that the longitudinal isosceles trapezoid becomes two parallelograms, where the head and fins of the small fish are folded.
13, turn the small fish origami to the front, draw eyes in the right position, or draw some patterns on the fish to make the small fish more lovely.
14, you can also fold the small fish with different sizes and colors of paper and paste it on the paper, so that the baby can use his imagination to make a three-dimensional sticker.
