Some more ideas
I just finished my sewing room in the basement. I did all of my own wiring. One thing I did do was decide where my ironing board would be used. I had those plugs higher and on a separate circuit. Irons pull a lot of power and if you have a computerized machine you don't want them on the same breaker. I also have two circuits going around my room. One for my machine and one for other things such as heater or floor lamp. No competition for power that way. I did put my outlets a little higher off the floor for easy on the back access. For my lights I used 4 bulb 4' light fixtures and they are perfect. But this is a basement so more light needed. If you plan to have a TV put on the wall have the jacks and power outlet put in the same vicinity so you avoid the cables hanging down. Hope these ideas are helpful. Enjoy your room!
