Many of my biomorphic forms are inspired by seed coat morphology - especially of parasitic plant seeds. Castilleja seeds are interesting to me in that the outer seed coat separates from the inner, which results in a skeleton-like appearance.
I just completed this little form in time for the 2019 American Association of Woodturners symposium, which will take place in a couple of weeks. It’s made from a dogwood end grain turning, which gives the thin-walled elements a lot of strength. It’s 3.75 X 3.25 inches in size (9.53 X 8.3 cm). I will have it on display in the instant gallery at the AAW symposium, in Raleigh, NC (July 12-14).
