Quick and easy drawer organizers not from the store

I was in the process of setting up my home office when I hit a snag.  There were no containers to separate and divide the space in my desk drawers.  It was silly to drive out to the store right at that moment to buy partitions and inserts when I had other tasks to attend to, but I didn't like the idea of placing all my supplies and necessities in the drawer where they could all mingle, get mixed up and become frustrating to use before I was able to shop.

I sat in my chair, letting my eyes wander hoping to get some sort of revelation.  My gaze fell to one of the check boxes I just received in the mail.  That was it!  I had about four check boxes from various accounts in my possession.  Why did the boxes need their covers?  Instantly my problem was solved.  I now had a neat little space for my extra pens, my phone charger cable and usb drive (not to mention the battery charger) and a place to neatly stack my index cards and sticky notes. 

My drawers were now easy to use and I could see everything at a quick glance.  The large hard drive and various other over sized items didn't bury my little office supplies because they were neatly stored in the check box covers.  This reinforced the truth that organizing solutions don't have to be pricey and from the store...Two months later I have not gone shopping for dividers because my drawers work just fine with a home-made solution!
