I'm not sure if it's OCD, but I am the same. I put one on my external hard drive on a whim, and well... I wished I hadn't immediately afterwards, because now it seems kind of tacky. I suppose it's just personal preference, and we all have our ideas of what looks good to us. 🙂 What's weird is, I don't dislike seeing them plastered all over other people's stuff. If they are happy with it, then I'm glad for them. But my own stuff? Not so much. 😉 Cool idea with the coasters.
