HA, HA...GOT IT!!! It's the lamp shades. Looking at ours, there is a small band at the bottom and at the top that the light really doesn't shine through. Kind of like a seam. It might not be necessary, but if we modeled those two seams and made them less transparent than the shade, I believe it would look much better. What do you think?
Don't be satisfied with what you can do but rather strive to do the things you can't do!
Exceed Expectations!
