I did this in gel polish over acrylic nails. I did the acrylic nails on my own and someday I plan to post a video tutorial on how to do your own acrylics. It is so very easy and cheap! I was not a huge fan of getting acrylic nails because of the cost and damage it does to your nail. When you do it on your own it seems you don't need to drill the natural nail as much and it causes little to no damage.
Anyway, back to the subject at hand. I did not take pictures during this one, but it's pretty simple I think you can figure it out! Enjoy :)
