When I first saw an Asheville CD store saleskid flip open the hinges of a CD case to remove that annoying sticker from across the top of the lid, I was gobsmacked. Once I saw it, it seemed so simple -- why had no one ever shown me this before? Why had I not been able to figure it out on my own? (Part of my surprise being that I'm a notorious rules-follower and it's obvious, isn't it, that you don't take something apart unless someone told you it was OK?) The Proper Discord blog posted a great little video tutorial on how to unwrap the cellophane packaging from various types of CD cases. It's little bits of knowledge like this which makes life on the Interwebz worth living.
