I collect Rugby jerseys.
I have around 30, but I don't add many at the moment.
I also wear them most of the time at home and on the weekends.
Don't you get a bit hot in the summer?
I have quite a lot of books but only because I've bought them one at a time as needed, not as part of a collection. I also part with them when I know I won't use them any more. I don't collect anything because after a while, the stuff gets on my nerves. Wouldn't go so far as to say I'm a minimalist though.
