These are some pictures of the process I went through for my project.
When I took a look at Karl Blossfeldts pictures of plants, it was difficult to know which ones would be best suited for extracting an architectural pattern from. So I spent a lot of time just sketching on a large sheet of rough paper, trying to annotate and break down the forms.
After I had drawn the final form I had to sculpt it in clay. This is the model half-done.
This is the clay model when completed.
