Here is a video where Sean demonstrates how to customize your flowcord and leash. 

It starts with an overview of various attachment options, and include:

- Instructions for large o-rings: 3:19 (come w/ flowleash, recommended)

- Instructions for small o-rings: 4:10-6:20 (slicker more DIY)

Hope this helps!
