@zenobie - I watched about 6, and made notes about what was common between them all. I used a clipper set at #4 for the back and sides and cut dry. Then I wet DH’s hair and scissor cut the rest - scissor over fingers. I ‘chip cut’ to blend, but also did a little clipper (with the guard off) over comb to blend the top with the shortest of the sides and back.
The coolest part was how you establish a guide when you cut the front hair (bang or fringe) and do a ‘reverse Mohawk. It was so cool to see it work in practice.
There was one video with a really annoying teacher, but it had the most/best advice. I will link it if I can find it again.
