The tutorial for hand-made origami lilies is as follows:

Prepare a square piece of origami paper, fold it into a diagonal line, and then unfold it to form a cross-shaped crease. Fold the four corners toward the center to form a small square. Fold the small square in half diagonally and then along the center point to form a small triangle.

Fold the two corners of the small triangle inward so that they align with the base, forming a diamond shape. Fold the two corners of the rhombus so that they align with the two endpoints of the base, forming a small triangle. Fold the two corners of the small triangle inward so that they line up with the bottom edge, forming a small diamond shape.

Fold the two corners of the small rhombus so that they align with the two endpoints of the base, forming a small triangle. Fold the two corners of the small triangle inward so that they line up with the bottom edge, forming a small diamond shape. Repeat the above steps, folding the origami all the way to the last small diamond shape, then fold it in half along the center point to form a small triangle.

Fold the two corners of the small triangle inward so that they align with the base, forming a small diamond shape. Fold the two corners of the small rhombus upward to form petals. Repeat the above steps to fold all the small rhombus shapes into petals. Finally, unfold the petals and gently pull them to take on the shape of a lily, and a beautiful origami lily is completed.

During the folding process, pay attention to the position and direction of the creases to ensure that the final flower shape is beautiful. Be gentle when folding paper to avoid breaking the paper. You can choose different colors of origami to make lilies according to your preferences and needs.
