I just redid a sewing/office/scrapbooking room in our new house. I second the idea of lots of plugs, a laminate or wood floor and a design wall.
Because I sometimes like to change layouts and move things around I used Elfa shelving. LOVE it!!!!
We put in track lighting and it is working fine (used the Home Depot brand).
My other idea (after seeing Julie and Julia) was using pegboard for all of my scrapbooking tools. I painted it the same color as the wall to blend it into the room. My next project is going to be another pegboard for my quilting supplies (rulers, cutters...etc.)
Hope this helps, Kanoelani
