Burn Patch

So here is my first attempt. I have burned three sheets of thin acetate toghether with some aloe vera gel in between to symbolise the photochromic material which will change colour proportionally to UV absorbtion.
TIP: not sure if aneone is using acetate or any plastics but to melt it an iron is way too hot it eats through the plastic and makes a mess. I found a hair straightener on lowest heat worked well.
