I was sorting through old computer equipment and happened across some 3.5 and 5.5 inch floppy disk drive boxes, full of disks. Nobody wanted the disks or the boxes.
Everything was left out for the bin men and I returned to my room. I then noticed a pile of CDs and an idea struck me as I never like to throw things out without trying to recycle or reuse.
A CD in a square paper or plastic envelope is about the same size as a 5.5 inch floppy disk. I dashed down to the bins and rescued my 5.5 inch floppy disk box and now I have a nice neat way of storing my CDs. I even squeezed a few jewel cases in too.
You can, of course, store anything you like in your old floppy disk boxes, seed packets, for example.
