The storage tower was delivered last week, and my CDs and DVDs now have a new home.
It is around five feet tall, and should provide more than enough storage for the rest of my life. As I said, it swivels, and the side facing the wall is completely empty. Even the three sides that are visible still have plenty of room. I took various knick-knacks... mostly handicrafts from my trips to Mexico... and books to fill in the empty shelves.
Everything is now neatly organized. The DVDs that I have made of pictures from my travels (36 in total) are all on the top two shelves to the front and arranged chronologically. My classical music CDs are all together and alphabetized by composer... Mexican music CDs are all together... etc., etc.
The only downside is that now I will be tempted to buy a lot more stuff to add to my media library!
