I have a ton of pins from years of punk shows and crafts shows and ones friends have sent me and they were sitting in a jar where I couldn't enjoy them. The solution was to take a frame I got at a thrift store, take out the crappy flower art and the glass and take some cork board (bought in a roll at the craft store) and glue it down on top of the mat, let dry, attach pins and voila! Right now they are arranged by color basically but since it's on cork I can re-arrange whenever!
