Since I seem to be more prone to drawing in the evening (which also has not changed since I used to hole up in my bedroom as a teenager), I have been struggling with being able to see and trying to avoid the frustration of dealing with shadows, to no avail. My work is also very up-close and detailed which means I am usually hunched over without my glasses, for no pair seems to work for me. It's naked eye, close-up stuff. Plus, I'm just getting damn old.
Anyway, I recalled seeing this little doo-hickey (pictured below) months and months ago while perusing the web and looking at Japanese Embroidery.
It's sold in two pieces; the lamp itself and the cardboard house. You supply the 40 watt bulb. Anyway, all together it was $22 plus shipping and I will let you know if this is a help or a hindrance once it arrives. Certainly, one could make such a thing. But I did enjoy giving the Japanese Embroidery site some business in order to support what looks to be an arcane and rare art form. (One which exceeds my ability to see.)
By the way, the store site has a great quote in its banner: "The hands are the exit of the spirit."
