Hey, a solution that requires patience and commitment. And handwashing! : )
How about the old toilet paper roll cylinders idea and put two notches on one end?
chop stick holders.
I just noticed that chop stick holders hold the chopsticks about 1/2 inch, or 1 cm, from the table.I thought they might make good cable risers. They're cheap and made of wood or bamboo.You will need quite a few, so low cost is important.I've never used cable risers and I'm a bit skeptical, but this is might be a cheap way to experiment rather than let my uninformed bias rule!
