Bought a $12 pack of velcro ties from Target and they beat the zip ties I'd used for 10 months
My desk was a nest of power cords and two HDMI cables running to a monitor, and I'd been tying them with zip ties I got from the garage. Problem was every time I swapped a cable I had to cut the tie and start over, and the plastic nubs poked my feet under the desk. Spent around $12 on a roll of velcro ties at the Target on Elston in Chicago back in March, and they've been worth every cent. Now I can undo one in two seconds, add a cord, and wrap it back up without scissors. I also stopped bundling the power strip cord with the video cables, since that cut some buzzing from my speakers. Curious how people here handle the rat's nest behind a TV stand where you can't reach the back, because velcro isn't helping me there yet.
That Elston Target runs out of those rolls fast, I had to hit the one on Roosevelt twice before finding them in stock. For the TV stand problem, the move is to pull the whole thing out once, do the velcro wrapping while it's out, then slide it back. Sounds like a pain but it's like 20 minutes and you never have to reach back there again. Label the ends of each cable with a strip of masking tape before you push it back too, that way when something acts up you know which one to grab without guessing. The real trick is leaving a little slack loop at the back so you can pull a cable out partway without unplugging everything.
