Again, working with Cathy from ~godsavethequeenfashi , I made these entertainingly floppy disks for one of her green lantern costuming projects!
These are cast in DragonSkin silicone rubber, and were sewed down to the Jacket. This is sized for a Guy Gardner costume.
The sculpt was done in sintra, with bevels underneath the undercuts around the edges to help keep the colors seperate and crisp, and to hide stitching it needed to attach it to the jacket.
The "shinier" one was a test using green pearlescent powder as an additive, and wound up being used as the final selection.
