my progress when taking off the tinfoil (very difficult to peal tinfoil off)
Here are my plaster texture results! It was very difficult trying to peal off the tinfoil from the plaster, and also taking off the tinfoil off the foam board because I used cement glue to glue the tinfoil and the board together, in order to keep the tinfoil from falling. Although I was not fully able to take all the pieces off, I did manage to get some pretty pleasing texture results (all pictured above). The pieces were thin, but the texture is visible and easily felt when touching the plaster pieces.
