Yeah but you would also be saving on space if they were on display. Mine are in cabinets 100 centimetres wide and 196 centimetres tall which means they would take up the same amount of space in a cupboard out of sight. The only difference is that I can see them behind glass which is better than not seeing them at all.
My cabinets cost about $700 each (they're both pine) but you don't have to buy something that expensive. There are some good alternatives available.
