In Connecticut, my studio is about 10 X 20 feet. I have shelves and drawers of supplies (found objects.) I have a rolling cart and an industrial bin with indiviual baskets to hold sorted materials.
Not so at my winter home. So I make do. (I'm not complaining. It's 84F and sunny here.) My space is about 6 X 8 feet. I have one storage box for supplies. The found objects are sorted by color (like my home studio). I put the bags and containers of the colors I'm using currently in a chair beside me. When I have company for dinner, I put away my studio is about five minutes. It works for me. (and my studio in Connecticut is not heated -- brrr.)
