Sometimes I forget when I'm assembling a card front to put the brads in BEFORE I adhere the paper!
An easy solution, that I used on this card, is to take a black gel pen and my mat stack from SU, color in however many circles you want for mock brads. Then, using Glossy Accents, just put a drop on each of the black circles you've colored. When the GA dries, voila! you have some "brads".
Since the Glossy Accents dries totally clear it can be used with any color permanent marker to make faux brads.
