The process began with the production of 25 flat shapes. These were contemplated and filtered before a single shape was selected. 

After some trial and error, I came to the understanding that I could notch the flat shapes and fit them together into 4-piece cross shapes. Two of these crosses were made. 

The two cross "halves" were then joined with 2 metal rings in the interior and exterior. Realizing that there were problems with stability, 4 more rings were added into spaces on the outside that opportunistically were a good size to accept the rings and hold the whole piece stable.
