I've been collecting good vintage/retro/antique furniture sites:
* The Old Cinema - I love this place, in Chiswick.
* Baileys Home & Garden - need to take a road trip to visit this one. I want to get some old apple crates to use as bookshelves.
* Castle Gibson - furniture and props
* Petersham Nurseries - garden furniture. Impossibly pretty. I can spend hours and hours here.
* Factory 20
