I'm super impressed that you are knitting a practice swatch to 'learn' this brioche stitch.
Brioche can be very hypnotic! Once you get your mojo rolling...it will sail along.
It isn't for TV knitting, that's for shore!
Here's a really cute scarf pattern that is 'reversible' and uses brioche with cables. One of our KH knitters posted hers here, and I loved it so much I had to do one, too! But it was a challenging learning curve, to be sure!
Before I started my scarf, I researched 'brioche knitting' like a mad scientist.
There were lots of helpful websites and youtube videos to help out!
It's a free pattern, too.
