If you answered yes to either one, then you have all the materials that you need to start making floppy [anything you want], as long as you already have a gluegun and some glue.
This Instructable is not so much a how-to guide as it is some basic ideas to show you what you can do ( and some of the basics of working with floppys of the 3.5" species)
I hope this fuels your imagination, and shows you what you can do with what seems like trash.
If you don't want to make anything out of any floppy that is special, use another - I found gems like Day of the Tenticle, Win 3.11, and MS Flightsim 5.
Step 1: Desk Organizer
These retail for quite a bit of money, but this is free!
Mine has 4 compartments, one with 2 'drawers', one for a bigger object. the other 2 are for pens/tools.
You can arrange yours anyway you want, but 2 floppys should be as deep as it goes, any deeper, and it'd be too big for your desk. These are quite free-form, like any of these projects. It all depends on what you plan on using it for.
