How to cut your own hair to save money

I was about to cut my hair, as I do about once/month or so, and figured I’d share some of my techniques. Cutting my own hair for roughly the last 10 years now has saved me time, lots of time, money, lots of money, and is way more custom. I have run into issues of bald patches here and there, but it’s always fixable for the most part. However, one time I did create a few too many patches that were too deep and had to have them filled in on a daily basis by my girlfriend for about a week with an eye pencil that matched my hair color - less noticeable. Anyway, that’s that and this is this.
