It's true that most of the time a hook is obscured by the thing hanging on it, but that doesn't mean it shouldn't look good when it does make a show. In fact, a wall hook can be to the eyes what a musical hook is to the ears: candy.
5 candy hooks to get a list started:
• Flip Hook
• Peel Adhesive Hook
• Broom Hook
• Accordia
• Ona
You have to include the Hang It All by Eames, it holds everything and anthing.
I'm partial to the Atlas Craftsman hook; I just put a couple of them with the bronze finish up in my apartment. It's not modern like the others, but it looks clean with some interesting detail.
