How do you fold a Petal Fold and is there a sizing guide?

Step:
1) Fold 1 petal over the bump side of the score. Lightly press to set the crease. Return 1st petal to open. Repeat for each individual petal.
2) Fold each petal back over the bump side of the score, in a circular pattern.
3) Carefully interlock the last petal with the first petal.
4) You're done!
