Gallon Ziplocs with folded over cardstock sheets for labels, also keeps them rigid so bags of cables that aren’t full don’t get buried. I have two bins, one with common stuff in my office and the other stays in the basement with all the weird cables.
I considered that but it poses a usability issue in that you have to manage the bags a lot more. You’d end up with empties or having to re-label and unnecessary overhead is the #1 cause of death for organization systems. I wanted something that I can grab a cable, and put it back in the bin with minimal effort. Wrap it, find the matching bag, insert, done. The vertical “filing” system makes the accessibility much better than a bin full of loose small bags with single cables.
I also only keep around 2 or 3 extras of most things other than super common ones like USB C cables. You probably won’t ever use a 50 pin SCSI cable ever again, and even if you do, you probably aren’t gonna need 7 of them.
Hard agree on multiple cables per bag.
I ziplocked my cables a bit ago and I actually ended up with surprisingly broad categories like “monitor cables” and “USB dongles” because I tossed a lot of my duplicate cables in the process. Since then I’ve had zero trouble finding the cables I’m looking for or figuring out where to put the cables I continue find around the house.
