Children's candy can be collected here. Prepare a 20cm*20cm patterned cardboard, fold it into a rectangle, then fold it into a small square, draw a "cross" in the center of the square ~ fold one corner of the rectangular cardboard in the cross direction, and finally make a bunch of flowers ~ cut off the excess part of the origami along the crease, and it will be a pentagon after unfolding ~ fold the five corners of the pentagon inward, and then fold the new one.
