Brioche Youtube Resources
Brioche is MUCH easier than it seems, it's essentially knitting a stitch with a corresponding yarn over and working each row twice. It creates a beautiful fabric and is well worth learning.
These are the videos I watched as I tried brioche for the first time. If it's not clicking for you, I encourage you to try the next video - you'll find a teacher who speaks to you and helps it make sense! I also found it helpful to grab some leftovers and just try knitting a swatch without the pressure of using your project yarn.
