I have convergence insufficiency, which means my eyes go wall-eyed when focusing close up, so I have glasses I wear for close up stuff. I'm constantly taking them on and off, and the nose pieces tangle in my hair if I try to move them on top of my head.
Finger knit a chain from pretty yarn. Cut two tiny washers from a silicone cap from one of those cannabis vape cartridges (spouse's vice, so always a couple lying around). Tied chain to washers, slid washers over glass's arms, and voila - an old lady glass's chain! Works like a charm in the evening when I'm going back and forth between TV, reading, crafting, what have you.
I also started making a big old length of fabric twine from scraps. Want to try my hand at making a rope basket, but don't want to buy rope.
