Did a little experimenting with pre-made metal rings to see if they would look nice and work well. And they did! I hot glued them directly onto the drywall mud papier-mâché skin of Cat Form #1 and then tack welded them into place. So much fun! I only picked up 16 rings for the experiment but if I had bought more I would have been there all night. So exciting!
Buying more rings today!
