For my first attempts, I made 3 separate models from 80gsm paper. Model One used strips of paper of increasing size folded and pinned together to form the flower. Model Two used diamond shapes of varying size slotted together to create a curved form making up the petals of the flower. Model Three was a origami model that i made which ended up with varied sized petals.
My final models followed the Fibonacci sequence (1, 3, 5, 8, 13, 21...) and appear more proportionally correct. The first model followed the same method of Model One in my first attempts however this time i made the smallest petals 10mm wide and 30mm long, the second layer of petals were 30mm wide and 50mm long and so on. The second model used diamonds of decending size to create the shape of the petals. They, too, used the numbers of the Fibonacci rule to guarentee more correct proportions.
