I am pretty excited about how this turned out! So excited that I've managed to forget how much pain it put me through as my fingers were frozen and my ribs were rattling around because it was so cold.
I found this tutorial on how to make light painting stencils and I've been wanting to try it out ever since I read it. Luckily I work in a drama room for a block a day and came across a stack of crumpled up cellophane used to change light colours. I carved the butterfly into the lid of a shoebox, taped the coloured cellophane inside and then used a flashlight inside the box to illumunate the butterfly stencil. You should try it!
