As a constant hunter gatherer I collect materials from anywhere in order to use later.
Sometimes an object can languish for years before a use occurs to me. I think that one is required to completely empty property for sale now but in the past people moving into my properties would find sheds, cupboards and attics with boxes and piles of odd things and other even odder objects which might, sometimes be mistaken for "art". Plaster filled rubber gloves, strange masks and entangled mobiles.
Some of my childhood "Mixed Media Constructions" of wire, plaster, broken glass and dismantled clocks are still around my parents house and garden.
