I've never particularly enjoyed getting my hair done for events — I always get this nagging feeling that I could've done a better job myself (and saved a ton of money). So for my sister's wedding, three of my cousins and I decided to skip out on the morning salon trip and do our own hair (with my sister's blessing, of course!). We spent hours trolling Pinterest for ideas we felt were within our capabilities, scheduled a day for trials a few weeks before the wedding, had a Target shopping spree for curling irons, bobby pins, and combs, and got to work.

If you're thinking about doing your own hair, either as a bride or as a bridesmaid, here are the most important things we learned:
Practice, practice, practice
Yes, it sounds obvious. But when I say practice, I don't mean trying the hairstyle once or twice. I must've practiced my hairstyle at least 10 times before the wedding — and I was going for a very simple look. Try following the same timeline as the wedding day — do your hair in the morning, then see how it wears throughout the day. That way, you can troubleshoot any problems.
Also, make sure that you practice every detail of the hairstyle — including the curls. I made the mistake of not testing curling my cousin Rachel's hair, and the curls practically fell out before the ceremony (sorry, Rachel). At least the top still looked good!
