I have collected many things over the years. Among my collections (though I am no longer actively collecting) are:
Souvenir demi-tasse spoons from places I've been;
Sew-on patches commemorating various locations I've visited (affixed to a special 'patch jacket,' and when that got filled, I started putting them on my old high school "senior sweater");
Postcards from places I've been;
Vintage cat postcards I collected in my childhood--they are anthropomorphic scenes of cats in humorous family situations--most were created in Belgium;
Miniatures of almost anything from antique Cracker-Jack toys to modern reproductions of things like antique hand-grind coffee mills.
I had to stop when I ran out of display space and most of my collectibles ended up stored in boxes. :-(
I have too much stuff to count....
