First the whole design was applied, which was then wrapped with paper so she could sleep overnight with the paste on. Doing this makes a darker stain than scraping it off before sleeping.

This is the finished mehndi, with gold gilding and red glitter. It matches her dress perfectly!
The second two photos were taken by Greg Harring, an amazing photographer.
