Garment fashion terminology
If I ever get completely on board with the "gallery wall" idea - a big "if" - I'll use this.
Folding wall table. This wall table is one of my favourites of all time. It is so clever designed, and the finish is over the top. When this table is folded up it looks totally like a picture, and when folded down the image hides below the table!
Love the drop down table idea. You could have folding chairs that hang on the wall and just get them down when you need them.
