I used to cut DH's all the time but then one day he decided it was time for a real haircut and I was so thankful. Now it looks like I'm back to doing it again because he is really in need of it. Starting to look like Scooby Do Shaggy.
I've trimmed by bangs before and have used the dogs grooming shears to cut my son's hair a few times when he wore it very short. It turned out good. Now days he wears it long, like Jesus long.
