The ladies have the right idea about the lighting. My suggestion is white paint especially on the ceiling. Semi gloss white is easier to clean and reflects the light wonderfully. My sewing room isn't white white, it has a subtle hint of yellow in it. Kiwi frost I think was the color.
We painted the shop all white and hung up the light fixtures and the change was dramatic. What an increase in light and we didn't have to buy extra fixtures.
Just don't go over board with the lights.
