I keep mine in a CD/DVD holder, but it holds the CDs vertically (side by side), so width doesn't matter. My desk also has a horizontal CD holder attatched to it, in which I have some of the regular CD cases. When I got LOVEppears, it sat on my desk collecting dust until I got the CD shelf. I have the shelves organized by genre. How dorky am I?
Here's a pic: (keep in mind, this isn't mine, its just a pic from Google Images)
The only problem with that CD shelf is that the obis keep falling off, and they get run over by my desk chair or almost get vacuumed up.
