We found Claire's updated CD case on her blog, Needle Book and had to take a closer look. She mentions that when she initially bought the cabinet, she had grand ideas of wanting to add fabric (but had no knowledge on how to make that happen)...
At first, Claire was thinking tension rods and then, while shopping she came across simple, white curtain rods with brass attachments. The real secret to the rods staying put is double sided tape! Claire has done a great job of making the CD cabinet feel less cluttered by covering up what's inside with decorative floral fabric.
