Researching the topic was not easy. Googling the topic USB cables and about any type of search I could dream up was pointless. I have learned to use YouTube to search for "how tos".
However, the best solution I could find for how to wrap up or roll these Apple lightning cables was to use a $4 cable gadget. I liked it, but I have 650 iPads.
So, this nylon strap may be the best.
I tried rubber bands, but they dry out during the school year and have to be replaced. Baggy or twist ties was suggested. However, the wire in these ties requires too much time to attach.
Nylon zip ties are strong and easy to apply. The photo below illustrates what it looks like.
This looks better than the rubber bands I used in this cart.
