Previously, I've shared a pictorial on how to clean up your cuticle post painting. I thought of posting up a simple video tutorial on this one as well.
So here it is.
My apology for the bad lighting in this clip. Hope this tutorial helps nonetheless.
This needs practice just as applying nail polish requires lots of practice to get nicely painted nails without much mess. I agree with most nail artists that the best way to get a perfect painted nails still lies in the skill of applying nail polish on nails so that you will get neater painted nails without worrying much about cleaning the mess.
So yeah, practice away!
