A. If you are having an updo, slip the teeth of the comb under a secure curl. Once the comb is slipped in, bobby pin over the teeth. The comb should match the curve of your head. Slide the comb in while holding the style in tact.
B. For short hair or down styles, take a two inch square section of hair from the area your veil will be attached. Take a brush or comb and tease the section of hair closest to the scalp. The idea is to form a cushion of matted hair. If your hair is thick, simply slide the comb in the matted section close to the scalp. Bobby pin over it.

C. For finer hair it helps to lay the matted section back. Pin the matted section to the scalp with a criss cross of bobby pins.

D. Now slide the teeth of the comb along the scalp UNDER the bobby pins. The teeth will go into the cushion. It should take a little muscle to slip it in. Add more bobby pins over the comb for heavy or long veils.

Where should my veil be placed on my head?

For the most part it is a matter of personal preference. Some brides like to "see" a lot of veil and some like it tucked in the back. In the photos below the pink arrows show a number of choices for each hairstyle. These brides below chose the first arrow.

 

Here these brides chose to show off a pretty tiara and a few curls. The veil is placed at the second arrow.

The third area is more toward the back and falls "off" the style.
