I prefer to sew during the daylight hours at my dining room table near a large window facing north. But of course I never finish my project before dark so I put some flourescent full spectrum screw-in type bulbs in my dining room fixture.... six of 'em. Almost just as good as daylight.
to bjnicholson.... it might be a good time to change your overhead light fixture and get one where the bulbs shine down instead of up.
