I posted earlier that I have the bendable one that has been shown in several of the links provided here. While the light is good, sometimes it's too strong/bright and is beyond what is good for my eyes.
I do use it at times ... and to answer questions, I do not find it moves around while I sew. Stays put wherever I line it up. That is, til I knock it out of the way as I move fabric around! OOPS!!
Wondering ... what about the small book lights?
Have never had one, but just getting a little creative thinking here.
Anyone use one?
