lets keep it on the insane levelThe definition of "crafty items" can be pretty broad depending on who thinks it is art and who thinks it junk but I've seen some pretty unusual items used. things like the guys who cut down bikes and used some of the parts in the tank or the person who cut a surfboard down to fit?
About as close to crafty as I get is wood and rock.
I tried making a styrofoam back wall one time but it looked like somebody tried to imitate nature so I quit.
That's where we may all have different ideas of what is insane and not? Some of the things that I have used might fit into either list!lets keep it on the insane level
