When I was at secondary school, I remember having a plastic key coil, with a belt trigger hook, like the ones shown in the image below.
During recent days, I‘ve been thinking that perhaps I should invest in one for my needlecraft scissors, as I seem to have developed a habit of misplacing them. The other option is to invest in a long chain (as in jewellery), which my scissors can be suspended from.
For example, late yesterday afternoon, I had taken my scissors from the lounge and into the kitchen. I was about to go out, and was in something of a rush, so instead of putting the scissors back in the lounge (where I would see them), I had put them in a drawer where I keep my kitchen scissors, without thinking.
Several hours later, when I needed to use the scissors again, I drove myself potty trying to remember where I had put them. It was a good 12 hours later when I eventually located them.
