all i could find was a slightly neon-toned yellow paper. we put out yellow crayons and pens to soften the color a bit.
then snowflake style, we offered the preschoolers a paper folded in fourths with one petal shape drawn on.
some thought they worked better as airplanes.
then gluing them around a center and adding an O shape for the middle with a cardboard stem.
our state flower!

Thank you for sharing this. Do you have a template for the petals?
