Unfortunately, I don't have what you would call a sewing room. I have about 1/2 of our spare bedroom. The other half is set with a bed and nightstand for guest.
My sewing machine is set up in the living room and DH sets up the extenstion table when I am needing it.
I do my cutting from our dining room table
We live in a modular/manufactured home, and even though we have 3 bedrooms, one is all ready a computer room
