I collect nutcrackers, paperweights, and kaleidoscopes. That said, I am like Adamae. At my age And on my own, I have stopped collecting but I have made a list of all my collections with prices paid so when I am gone, my kids will at least know the value of my stuff. What they do with it is up to them!
I probably should add quilt patterns to my collection list although they weren't intended to be a collection! On my behalf, I have actually made some of them but an awful lot were "someday" purchases and someday hasn't gotten here yet!
