What do people find is the neatest way to hang pictures on a plaster or masonry wall?
I usually use the picture hooks (available in all cheap stores) with a steel (or strengthened) nail which has to be hammered in. But these have the disadvantage that a piece of plaster often comes away with them if one tries to pull out the hook.
The alternative I've taken to is to use an ordinary hook screwed in with a very small rawlplug. If the rawlplug is pushed in a little below the surface it is easy enough if one takes out the hook to almost hide the spot with polyfilla or similar.
But what do the experts advise?
