I'm lucky to have a studio in a beautiful old factory building which is shared by several other artists. Each space is tailored to the specific work they do and we have a great exhibition space with perfect light and huge windows. Just before xmas we held our first exhibition with an awesome opening party.
I'll be honest, I'm not the most organised when it comes to my studio materials, but it works for me. Everything is where it needs to be, mostly on the floor!
