On mine: loads of postage stamps! I am working on a new postage stamps handbag and the only way for me to do this is to have all the stamps scattered around me. I know this will probably give stamp collectors a small heart attack, but I can't keep stamps in neatly sorted books and folders, organized by year or theme...no! I simply stuff them into boxes and envelopes and then when I start working I keep emptying box after box and rummage around till I find the perfect stamp for the perfect spot on the bag. Sometimes I lose track of what I am doing and end up staring at the mini artworks of countries that no longer exist, extinct butterflies, scientists from different eras. It's like walking through a history museum, but in the comfort of my own home. Some stamps are still partly attached to their envelopes, a far-away address still visible, and I wonder who sent them and what was written in the letters that travelled around the world. Funny how a tiny piece of paper can have so many different meanings, don't you agree?
