I just did some work on my first machine which involved pulling the liner out and I thought it would be a neat idea to put some things in between the liner. I put two pennies in there one from the year the machine was built and one from the year I did the work on it. I also put a picture of the machine in my dorm room. I thought that incase I had to pull the liner out years later it would be really neat to find these old things I put in the machine. Anyone else ever do this? Also I made sure to put the pennies in the machine liner where there are no wires at all and the picture is between two pieces of insulation away from wires as well.
