Great Lighting . I have mine lit up brighter than daylight( it is in the basement) . But put some on different switches so not all have to be on if not needed.
Lots of outlets- you may have your room configured a certain way now , but give yourself future flexibilty.
I would encourage you to have storage cabinets with doors, any light will fade fabric , it does not have to be direct sunlight.
A big cork board for holding directions , a few unfinished blocks, flyers, business cards, and photos of inspirational quilts or future idea.
I had cable TV put in ... a great feature .. now if there is a program I want to watch , I do not have to leave to room.
Just one other note : I wish I had put in a handsink... at least nearby...for washing may hands and filling the iron, testing for fabric running etc. This flaw in my plan will be corrected .. someday. I just wish I had done it when the space was being finished.
