To finish, I swiped a shiny topcoat on to give my nails a "wet" caviar appearance. Then, I just pressed the nails onto my nail beds. The beads stayed on very well because of the nail glue's strength, and although I wouldn't recommend trying to open a soda can while wearing them, for a night out, they should definitely hold together.
What I'd do differently next time: While the larger beads I used are great for demonstration purposes, you'll probably be happier using smaller seed beads. I'd also recommend making the nails shorter for real-life wear for something a little more subtle.
