Here is an origami petunia flower. I made it using purple/lavenderish wrapping paper.
The instructions for this particular flower can be found in the book “Origami Flowers: Popular Blossoms and Creative Bouquets” written by Hiromi Hayashi.
I make these flowers with 6″ stems made of floral wire and floral tape. The flowers themselves measure 1.75″ across in diameter.
