The folks over at Fine Craft Guild discuss the notion of making DIY clothes rack dividers. They suggest buying dividers (they're really cheap, but they come in massive quantities, like 50 or 100 per), using cardboard or, my favorite, using discarded CDs and DVDs. I'm thinking a hole saw to get the center hole to size and a hand saw to make the access slice. What do you think??
The dividers pictured above are available at Stork Delivery's Etsy shop (set of 5 for $17).
