Bobby Pins - Crimped side UP or DOWN?
I had always worse them crimped side up, and they always would fall out of my hair, unless I was using them to hold in a bun etc. But last night as I was getting ready to go to a wedding, I thought I might have a go doing it the other way round (As I had recently seen a pin on pinterest) and what do you know... they stayed in and I got compliments on my hair! They worked as well as any other clips!
Who knew? All this time... I could have been doing it wrong...
