Quick, easy and furnitures are not expensive.
One year, I made 40 to fix in hair for a dance show.
Bend in accordion on all the height.
Tie a thread in the middle.
(Plan enough length to hang on the flower when finished).
Cut out the side where the handkerchief was folded.
Unstick delicately every thickness of the handkerchief.
With the folding accordion, petals take of themselves a “creased” aspect.
