Like Kendall and some other respondents here, I like to hang a couple of my guitars on the wall. One is next to the computer as I sit here. The computer chair is comfortable, and its handy to read my songs,tunes or tabs from the computer as I practice-or as the muse inspires me.
I have a couple of instrument cases hanging around the living room, and a music stand and a shelf full of music books.
There are also a couple of pennywhistles in my pencil stand next to the monitor.
My wife doesn't mind : she keeps her upright bass on the landing of the stairs to the second floor, casually leaning into the corner and ready for playing at any time.
