Oh, I love your studio, and love the knotty pine. I have my sewing cabinet against the back of the living room couch, use the kitchen table to cut on, and so none of my messes are even hidden when I sew.
I also paint, and when I have my easel set up, it occupies the space between the table and the windows in the dining area.
It is living space. No room for creative messes.
To have your space, I wouldn't care if it had sheets nailed to wall studs.....just a space of my own would do.
Yours is heavenly.
