My lights are not directly overhead. They are placed to the front of where each of my stations are so the shadow will be behind me.
This is really good over my cutting table 'cause the light doesn't reflect off the rulers and no shadow from me over my fabric.
I do use a spot light on my sewing machine, pointed at the working part of the machine.
I also mix the type of F-tubes so there is a wide spectrum of light. No "OTT Lights for me, We don't live in Ott Light so choosing fabric under them actually distorts the finished look after you remove them from under this light.
Good luck finishing your room and post pitures for us to enjoy.
peace :D
