It has happened. We have moved into our new to us home and I have a sewing room. It is a big room that is as dark as the Black Hole. It has red carpet on the floor and an 1950's kitchen light to light the room. And it boasts cupboards where someone's hunting guns were stored. The only thing two things right are the size and the rug isn't glued to the floor.
Here are pictures of it just after DH removed some moulding, a small piece of the ceiling and checked the walls.

The east wall with the only window. Nice size window for a basement in an older home.

The gun cupboard, which will probably be removed to be part of the bathroom.

The west side of the room which has a large closet.

I got the lady's dress form and will be dressing her in a vintage dress from the patterns that were left behind.
Our plan is to paint the walls a light colour, the ceiling white, add a good ceiling light and to put down easy care flooring. DH found that the walls are insulated to the floor which is will keep it warm in the winter. Not sure if I get the gun cupboards or if they will be removed to add room to the downstairs bathroom.
And the next pictures are of the small bedroom across the hall from my sewing room and the second bedroom upstairs. Most of the items in those rooms will be put into my sewing room. Right now I have to sew at the dining room table. Lucky me.

Upstairs room.

Basement room.
The pictures are horrible due to the poor lighting and the dark walls.
