Mine isn't a specific object, its a library. I've got bookshelves in a corner right now. The holy grail for me would be a library with big windows, one of those spiral staircases, and books all along the walls. There'd be big cozy chairs to read in, and a small table for drinks and snacks. Bottom shelf would be lined with all the books I loved when I was young for my kids to discover. I collect fantasy maps right now because I love seeing how people visualize these worlds. So I'd have big map displays in between book sections with those maps. I go to lots of author events so I'd have little book stands with my signed books or books that are otherwise meaningful to me. And I'd decorate with little tchotchkes I've picked up from traveling.
