One of the most practical if incredibly ugly methods I have seen I will post a photo of and perhaps some extra photos on another thread - in the travel section.

I have photos somewhere, lost in boxes and boxes of old transparencies, but found a photo on the net. My wife and I stayed in Martindale Hall one weekend and had the run of the place at night. During the day it is open to the public, but if one stays there, when the public tours are over, one has the run of the place, can use the library, play billiards, can organise a gourmet cooked dinner. Accommodation was and maybe still is, is in the old servants bedrooms in a private wing of the house.

Anyway Martindale has a firearm, sword and the like collection. These are displayed on the walls using chicken wire or netting. VERY practical but not photogenic!
