If like me you have numerous USB leads then you share my frustration at finding the right one. I have two camera both with similar leads but with different connectors and when I'm in a rush I always mix them up. This short tutorial shows how you can save yourself more frustration.
All you need is the correct lead, a crochet hook and some spare yarn. I've used a 4mm hook and double knit yarn.
Start with a slip knit and place the hook on top of the cable.
Pull the yarn through to the front. Yarn over the hook and pull through the two loops on your hook.
You're making a double crochet or, if you're using American terms, a single crochet.
Carry on until you've added enough to differentiate between the cables.
Hopefully that's enough not to get them mixed up ever again!
