Instruments of expression

I was thinking that even though my primary medium of expression is oils on canvas, I have a tendency to keep all kinds of objects that have special appeal to me, in spite of their current pariah state.  I feel they tell me something, like a deeper meaning  that somehow would be revealed at a future time.  I know they would be transformed into something else at some point.    What are those?  Wooden wine boxes, cardboard pieces, wood pieces, stones, it is hard to explain but the common theme is "things that are different even within their own category."  They will eventually help me to express a thought, instruments of expression.
