I have this little plastic disposable cup that I pour glue or gesso into whenever I'm creating. When I'm finished I pour the excess back, and wipe up a bit with my brush, but I never wash it out. Hence, layer upon layer of stuff has dried inside of it, creating something strangely awesome. The other day, just for fun I pressed on the plastic until I'd loosened the inside and out it popped! Now I have two containers! I know that there are some sickos out there just like me, who are just as intrigued and fascinated as I was, who are very glad that I took a picture.
