Square origami is folded in half at two opposite sides and two opposite corners, and unfolded after pressing out creases.

After the opposite sides are folded in half, the two corners are folded inward according to the existing creases to form a triangle (double layer) with creases inside.

Fold the two corners at the bottom of the upper layer to the apex to press the crease, and then push the folded triangle down from the opening to form two small squares.

Fold the upper corners of the two small squares diagonally in half, fold the paper over, and repeat the above steps; Fold down the upper corner of the origami, press out the crease and unfold it.

Fold the paper from the opening under the origami to form an upper part, a middle part and a lower part; The two corners of the middle part of origami are folded outward and flattened in the opposite direction, as shown in the figure; Fold the paper upside down and erect the double triangle;

Expand a triangle with four sides, and press one side clockwise according to the existing crease; Pinch the vertex of the triangle, twist it clockwise, and rotate the folding angle of the periphery at the same time to reshape the rose at will. You can flip the lace at will to press the flower heart. Just adjust it to your liking.
