Malka Sabroe-JoHanson It is about 31" wide. I have to mention that I did a lot of research on finding and inspiration on designing this section but Martha Stewart had the best posted on her website years ago. She was wonderful in giving the sizes, dimension and sources s of everything here. I don't know it anymore but the thread rack came from an on-line sewing catalog. Good luck on this, the client loved this though and thanks to the creativity of Martha Stewart in always inspiriting me.
I like having the full wall of cabinet since it will be facing my kitchen and with a roll away table I could use for eating when it's only my husband and I. With a few drawers or shelves I could use it has a desk.
