I was really disappointed at first. A lot of the stencils seemed too large for my small eyebrows or too ridiculous for my face shape (I have a small face and the full arch is too much) and it just seemed too hard to hold in place. After watching two youtube videos, and messing up about 5 times trying to color in my brows to pluck them, I finally got the hang of it. At first I was using the Anastasia brow powder duo to color in the shape but it barely showed up and I couldn't tell where to pluck. I ended up using an eyeliner to make heavy trace marks then I plucked around the shape. After washing off the tracing with makeup remover, my eyebrow shape looks great-- like they were professionally done! Be prepared to be disappointed that not all the stencils will work and be prepared to mess up a few times before you get the hang of it. In my opinion, as long as one or two of the stencils work and you get the hang of it, it's still worth it because you'll be saving time and money in the long run from making trips to the salon.
