Most archery shops sell screw in hooks that are no scratch coated. You can essentially screw them in anywhere, doorframes, etc. I like the inside frame of a closet with folding doors so it's out of sight too. The Mrs. is not happy decorating the house with "gear" like Mrs JC is . I put a flintlock on the wall in the bedroom once, prettiest Kentucky rifle you ever saw, and she refused to sleep there until it came down. IT was a tough decision, mind you, but she won, that time.
Down in the office I got 2 lengths of 1x6, varnished them and screwed them upright to the studs 36" apart. Then I got those screw in hangers from the shop and screwed them in pairs up the length and we can hang all the bows there.
I have one inside the frame of the bedroom closet.
