THe idea was to use recycled paper and materials and to stay on the tones of sand, white and brown.
I think that one of the most beautiful flowers I could use for this purpose is the Carambola, by Carmen Sprung.
It is not a beginner model, but everybody can make it with some practice. It is perfect to do with recycled paper. In this case I used old bags from Zara.
If you want to practice on your own, i suggest you to use the instructions by Sarah Adams, that you can find in the link below.
She has a beautiful origami channel and is very clear in the explanations.
As you can see, she arranges the flowers in a slightly different way, but I preferred to have a softer star in the center.
