I too collect paper ! I love quotes so guess that is a collection. I love books and have bought many at thrift stores and have many from 'Simple Truths' they are great. My most prized collection is my music box collection. But it is beginning to look cluttered so I have not bought any for about a year and have begun giving some of them away as gifts. Have about 150 of them so really need to cut that amount back
I have also begun giving away other 'stuff'. Much of it I really do not need any more.
