These are plasticine models of the shape and form of the main body of a poppy seed head.
This drawing is from the plasticine models.
I used white pencil on black sugar paper. I chose these media as I could simplify what I was seeing and concentrate on the main forms and not any surface details.
Support structure. Separate curved legs joining in the centre.
The inside section is a curved cup form. It does not have a flat base so it needs the support structure to stand up.
Faceted surface with separate flattened sections or a rounded surface all the way round. the texture is smooth to the touch.
