Step 1: Fold the Square Into a Triangle
0:33
Start with a square sheet of origami paper, pattern side down. Fold it in half corner to corner so you get a triangle, then open it back up. Fold the other diagonal the same way so both crease lines cross in the middle. Run a bone folder or your thumbnail along each fold to make it crisp. These two creases set up everything that comes next.
Tip
Patterned paper looks best because the print shows on the finished petals.
