For reference:
To make the hatpin, I used Sculpey to form the black spike at the end, forming it over the head end of a 5" hat pin. Since JoAnn's only sells those in packets of 3, and allowing for the risk of damage in the forming/curing process, I went ahead and made 2. I could not find teardrop shaped pearly beads in time for the con, so I went with a basic round shape, and hit it with some Krazy Glue (the Kragle!) to stay in place. The final stage was to add purple flowers, daisies, and dark and light cherries to the hat. In retrospect, it also needed netting around the crown, but I stitched the flowers on, so I will have to go back at some other time to add the net.
Next up, my MPDA... I cut the shape out of several layers of balsa wood, and used the original prop design image (not totally SA, since the final version was more silver), and mod podged it to the (painted) wood. For a 3-D effect, I cut the "lens" side into two layers.
For Missy's cameo, I continue to be on the quest to find the simple-edged cameo setting used onscreen, but lacking that, I went with this ebay find:
I believe the closest match to her spiky bracelet is this little number from Hot Topic, but since I came across a thrift store find that was "close" when I was still shopping hats, I have not purchased this... yet. I might not since future evolution of the costume appears to drop the spiked bracelet.
The cyber bracelet is on my "future projects" list. For the time being, I have been using a plain silver colored cuff bracelet. It's delightful, turns my arm a lovely shade of green *smirk*
