I had a pile of rubber laying around from back in the day that I made rubber jewelry. What to do with a pile of sturdy rubber? Make a corset ofcourse!
Sadly, my sewing machine was no match for this thick material and I ended up buying myself some leatherpoint needles and sewing the entire thing by hand. I also added some reflective tape to the seems. It looks awesome under a stroboscope.
If you have any questions, feel free to ask.
