How to secure a veil?

Are you wearing your hair just down? Half up? If all down-tease the hair at your crown a bit to help the comb on veil have something to slide into. Also place your Bobby pins in an X with the ridge side down. You can also use an extra tacky hairspray to spray your bobbypins to help them hold better.

If half up you'd do the same process but it would hold a little better throughout the night since it would give your hair just a bit more structure.

Hi Kay! That makes it even easier! The more structure your hair has the easier it will hold in your hair all night. If you place the veil on top of your bun-there will be lots of support and spots to pin in. Placing it under can also be done but would require a bit more pins to secure. Just depends which look you are going for!Good luck!

So it really is as simple as sticking a million bobby pins in my hair and some hair spray?
