My husband built my first sewing room in the garage. I had a space 6' X 8' and it was perfect for me for 10 years!
I had a small AC, a space heater, and a stereo. One whole wall was a table he built for my sewing machine. He cut a hole for the machine so the table and sewing surface were even. The wall in back of me was floor to ceiling shelves to house my fabrics. Hanging shelves over the table gave me room for all the other items. I loved it!
I have since moved into the house, because the last child was gone, and DH decided he wanted my room to store his stuff.
I have much more space now, but I really did love my little room...
