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.
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.
