Thank you! I ended up giving in and going to a salon, where it would just take them 20 minutes to do what might take me a lot longer.
I got an inverted bob, which looks cute and will be cool for summer! I have layers on the sides too.
It was interesting because to start the cut, she combed all of my hair to the back, as though she was pulling it into a low ponytail, and made her first cut that way--just like the ponytail method in the video!
