2. Avoid painting your skin
It is fairly common to paint the skin just above your toenail when working on a pedicure. This gives you the annoying task of trying to eliminate the nail polish later on from your skin. You can skip the whole issue by just slipping a bit of newspaper under your nail.
If you cut it to be slightly curved, the paper will fit better. When you slip up, the paper will be painted, rather than your skin. Toss the paper at the end of the session to enjoy nice, neat nails.
