I found photos of a delightful sea urchin shell on the internet several weeks ago. It is commonly known as a Sputnik sea urchin for the pencil-like projections it has while still living.

Those photos inspired me to design and paint a net for assembly into a paper solid.

a plan to cut out, score, glue and assemble

Then I made several sea urchins and took photos.

I hope you like my sea urchins.
