For me, it's not often. Not because I don't enjoy it. My machines are not permanently set up, so it's an ordeal to bring it all down from the high shelves and set it up. Plus, my wife gets bored with it all. It's kind of a loner hobby for me. Sometimes, my daughter will watch too, but frequently gets up from the couch before a reel is over. I suppose that I watch once every week (or every two weeks) on average. Please don't crucify me!
