I don't have any books or videos (sorry!) but I do cut my own hair.
It's rather thick, but I keep it short and choppy. The one thing that enables me to cut my own hair and hide my mistakes are my razor scissors! Available for sure at a beauty supply store but I think I got mine at a wal-mart. If your kids are little with that baby fine hair, I don't know if this is helpful, but it really helps me save money.
