What an awesome studio. As an old retired "school marm" I can think of only one thing that is missing. Does it have the "smell" of a school room? There's something about walking into a schoolroom and taking in all the scents -- books, paper, chalk, etc. Yes, it's been 12 years since I retired, but I still miss "my room."
Your hanging rod for your quilts gives me an idea for my room.
