A requested tutorial for a balaclava done on a circular knitting machine!

Wear it 2 ways!
(This is not for a rank beginner!) Skills needed:
~ Basic Circular Knitting Machine Skills (casting on/off, color changes)
~ Hand knitting OR Crochet skills
Essentially, it’s a long tube (like a reversible hat). One end is closed like a hat, the other end is finished with a stretch bind off. Waste yarn is inserted in the middle of the tube to allow for the face opening. Simple concept!
