Square origami can be folded into weapons such as thunder axes, paper guns, darts, sniper rifles, etc.

Steps: We first take a 21cm square piece of paper, we fold the four sides in half to form the mountain line, and fold the four corners in half to form the valley line (as shown in the picture). Steps: We pinch the two sides together and flatten them downwards, and a "double square" shape will appear. Steps: We fold both sides in half to the middle line, folding one step just to deepen the crease.

Steps: After folding it in half, we will find a diagonal crease on each side, and at the same time we open the inside, like an open mouth. Steps: After unfolding, fold the two sides inward along the crease. Steps: We fold the previous layer forward.

Origami Pikachu: Prepare a square piece of yellow paper and fold it into a rice-shaped crease; pinch the crease and fold it into a triangle, and fold the bottom corners of the front and back triangles toward the top corners to form a square; align the left and right corners. Fold at the crease line, fold the top two corners down, and insert them into the triangle; turn over, fold the left and right corners toward the middle, and fold the bottom two corners outward; open the middle, and then paint the appropriate facial features, and the three-dimensional Pikachu will be Folded.

Origami heart: Prepare a square piece of origami paper; make two intersecting creases according to the creases below; continue folding the small rectangle on top symmetrically, and then turn the shape over; fold the Fold the upper part of the rectangle, follow the picture below, fold it left and right, and then flip it over; take the middle fold line as the center and fold the lower sides toward the middle; fold the lower part into two symmetrical small triangles.

Fold the upper and lower triangles together, as shown below. Don’t rush to make the crease first; press the crease here like this, and then tuck the upper triangle into the lower one. In the triangle; fold the two outer corners into a triangle; fold the lower top corner downwards; flip it over, and a heart shape is ready. You can apply double-sided tape and stick it wherever you want.
