Not that I’m the most talented person in the world at DIY French manicures - I used to do them all the time and was pretty good at them, but this one, as you can see, was a rush job completed during a much-shorter-than-I-expected-it-to-be nap - but there are a few little tricks that make them way easier:
1. Start with very little polish on the brush - you don’t want any rolling down and glopping onto your nail.
2. Begin the line at the halfway point and go to one edge of the nail, then return to the halfway point and draw the other side of the line.
3. Don’t worry about getting polish on the tips of your fingers - you probably will, especially if your nails are as short as mine. Just let it happen, and then run a Q-tip dipped in polish remover over any wayward spots after you’re done.
