They probably unscrew after you loosen the set screw. The bottom of the socket has a threaded hole in it.

Thanks - I hadn't seen those two sites before. I must be dense since I'm not finding bases listed separately, but I suppose I'll just call and find out if they do, seems like they should since they sell the shades separately. - Rob

The pendants look gorgeous in the kitchen. My only concern about your husband's fantastic pendants is that they may be too small for the pool table. I'm probably wrong, just wanted to mention in in case it mattered in the end. Lining bookshelves with grasscloth puzzles me a bit. Isn't the point of the grasscloth the texture and the point of the shelves to be filled, hence negating the texture? OTOH if you did not pay much for the bonus of having grasscloth, and all you care about it the color- awesome. I love it when shelves contrast in deep or bright colors. I think a small, taller table between the two overstuffed chairs will be lovely with new chairs. Maybe a tea table? I think you have a very cohesive space. I love your style very much- it's classic and warm.

So nice and relaxing shade
