It won't be long before magnetic MDF board is available for walls... I can't tell you how cool that would be for positioning photos!
I have strips of horizontal black metal on the wall above my desk. I got them at Home Depot for less than a buck per strip in the "wayyyy industrial" section (that's the official name) where they have big long ground stakes and crazy stuff only 300-pound sweaty men usually buy. They're black and neat lookin, they had holes in them so I could put a screw thru them and into the wall, and magnets stick to them like superglue.
Then I got black some clips with magnets in them; I think I got those at Target or Bed Bath & Beyond. I have a bunch of mounted 16x20s & award ribbons up there now (my WPPI print entries), but I switch them out to other stuff every now & then. It's fun to rearrange the clips & the prints, and it's so easy.
The clips can make dents in the prints, I guess, but I don't really care all that much. It's a changing all the time.. doesn't matter if they get a dent/ding in a corner from a clip.
