I'm glad I'm not the only one who cuts their hubby's hair! I've done it for about 5-6 years now and he also used to get his hair cut by his Mum before that. She used to use scissors. When I met him I used scissors too and it wasn't for a year or more of hour-long haircuts until I realised I was essentially giving him a no2 manually, LOL. So now he just has a no2 everytime he wants a haircut, a no0 to tidy the back and sideburns, and I tidy around the ears and forehead with scissors. I've pretty much got my technique down and after it has grown back a bit it looks pretty good I think. Luckily he's one of those people who suit short-short hair.
I've taken to cutting my own hair too in the past couple of years. I always wear it up when I leave the house, so I figured it wouldn't make much of a difference. I wet the hair first. I cut it in a dead straight line and get hubby to quickly tidy up the back a bit if I can't reach. Takes a bit of work to get right but does the trick of getting rid of any knottyness on the ends. Remember though that once dry, your hair often shortens, so don't cut it too short while wet. This year I got bored and gave myself a fringe too - also pretty blunt, straight-lined. Doesn't look too bad actually - I got quite a few compliments after I did it and people kept saying 'Wow, you did it yourself?!'
For those with longish hair, a knitted headband is really handy to keep your hair out of your face. I just made one over the weekend and it is awesome! It cost me pretty much nothing but a couple nights of work, because my Mum had a bag of yarn she no longer wanted. I have an (albeit very wonky) description of how I made it & a pic on the blog (http://wildschwein.wordpress.com
I am in no way gifted with knitting and this was pretty much my first ever successful knitting project, so give it a go!
