How to Easily Use Key Rings

For me, this is the easiest and fastest way to use key rings. 

How does it work?

1. take a string of yarn
2. put the yarn through the key ring
3. let the yarn get on the key ring by keeping it straight against the key ring.
4. let the yarn switch side as shown in the video
5. pull the yarn to open the key ring
6. let the key slide on.
7. twist twist twist and done!
