Often when using a zip tie one will put it around whatever your attaching once and then pull it tight and snip off the excess bit.
A friend showed me a technique that allowes you to reuse the zip tie multiple times in many cases without having to fight with the ziptie trying to undo its latch.
Step 1: How to Attach
When you have a zip tie that is too long, instead of cutting off the extra continue to wrap it around whatever your connecting multiple times until you have used much of the extra slack.
Step 2: Removing Ziptie
As you can see you are left with a zip tie that is still able to be used again in many cases.
This method is usefull when temporarily attaching items that you may need to remove and reattach later as you can see i was able to reattach the ziptie around the cable yet again.
