When I was young it was often due to necessity, but it is now a habit and I have a hard time throwing anything away. Most items can be used in many more ways than the were originally intended for.
One of my next projects was creating steampunk accessories for costumes. I dumped out my broken jewelry o to the floor and tried layer different pieces together until I had something that would look like a brooch.
I came up with three brooches. I used a glue made for metals that worked very well. It was very tacky and held the pieces together with out the parts slipping out of position until the glue set.
Its rewarding to take junk and turn in to something useful again!
