I collected stamps too, Lise. I used to send away to all these stamp companies.....loved it. (I still have my childhood stamp book, but now we've added hubby's fathers collection to it.....although I don't do much with it)
Now I don't have a specific thing that I collect, but I love all things Victorian, and antiques of any kind. I love miniatures. Miniature anything, but particularly antique miniatures.
