There are a lot of cable sorting solutions on the market. Some really edgy, some just cheap and practical. This is definitely a cheap solution, because most would have the supplies at home and it doesn’t even require a trip to Officeworks (which is a good thing!!!!)
To keep it in the same spirit, reuse and recycle, you can label them with a bread tie or a cloth peg
If you want a more permanent and transport friendly solution,LessMess sells cable labels that really stick.
