When I was redoing my sewing room I found a couple of web sites where people had posted many pictures of their sewing rooms. (Google is our friend!) Here's one of the sites.

I started collecting pictures of everything I liked. Then I called in our cabinet builder and showed him what I wanted. It's turned out nearly perfect.
Many of us have posted photos on this web site of our sewing rooms too. I know Jim's Gem's sewing room was one of my favorite and I have fabric cabinets very similar to hers. :lol:

My suggestion then is to just start collecting many, many photos.
This is my sewing room shortly after it was finished.
