Tool material: a square, a pen.
Step 1: Fold the square paper pair into a rectangle, fold the upper half of the paper in half, so that the upper edge of the paper is aligned with the lower edge, then press out the crease, then unfold the paper, fold it from right to left, fold the crease first, then unfold it, and a cross crease will appear. Change the direction, fold from right to left, fold the crease first, and then unfold it, and a zigzag crease will appear.
Step 2: Fold the two sides inward and turn them into two triangles.
Step 3: Fold one edge of the triangle into a small triangle, then erect the small triangle, open it again, align it with the center line, and flatten it down according to the crease.
Step 4: flatten the other three corners in the same way as above, and fold more than four corners into a diamond, with one sharp corner and one opening facing upward.
Step 5: Align the center lines of two edges of one face and fold the other three faces inward. The method is the same as above.
Step 6: Turn the folded side over to the same side and turn it into a diamond. Pull down the sharp corner of one side and align it with the bottom. Align the inner edge along the center line and press, taking care not to tear the joint between the two sides.
Step 7: Fold it into a picture according to the above steps, and fold the other three sides according to the same steps as above.
Step 8: After folding, the facet has an angle, the lower angle is turned up, which is two triangles along the center line, and the other three angles are also turned up.
Step 9: Fold the corners on both sides to the center line, and fold the other three faces according to this step. Turn the four sides of the origami upside down, align and flatten it.
Step 10: Take out a pen and put it on one of the corners, roll it in, start from the sharp corner, roll it in a few times, and there will be an arc.
Step 11: Follow this step for the other three corners, and the four petals will be folded.
The above is a tutorial on homemade bouquets.
