Here are some great affordable lamps to update your space.
Pier 1 - very chic in a bedroom or living room.
Pier 1 - Great as a statement piece or in a coastal house. Would also be great oxblood red.
The classic Pottery Barn. Always great in a bedroom.
Crate and Barrel - Mercury glass is always an elegant choice.
Garnet Hill - The finish is fabulous and or so Belgian.
CB2 Pendant - At the incredible price of $49 you can afford to use more than one. Just trim out the shade with ribbon or cover it in the fabric of your choice.
CB2 - Great kitchen or office pendant
Just a couple I found as thought starters. Ikea is always another great source for pendants or office lights.
Hope you had a great holiday weekend.
