The segments are cut on the scroll saw using marine ply wood in pic 2 an 3, there are approximately
between 45-60 pieces in each shell. Pic 1, I added purple heart and Osage orange segments.
The bases are pieces of Red Gum stumps.
Awesome job and welcome to the forum. Somewhere I have a tutorial on how to make these shells that I downloaded from the internet. Have not tried one yet, but hope to get to it someday.
