I was lazy to file all of my nails for this guide, but i usually file them in the rounded corner square shape like in the picture above.
Paint your tips with any colored nail polish. I chose baby blue. Make sure it's painted evenly.
Once all of your tips are painted, pour a little bit of nail polish remover/ acetone into the shot glass/small container. Get your brush ready.
Dip brush into nail polish remover and slowly brush away excess nail polish and start shaping the nail curve. I apologize for the pour video quality. My cousin cant record videos lol
Acetone/nail polish remover dries quickly so u might need to pour some more into the dipping container.
This is how it looks after shaping it.
Paint the top coat and youre done. :)
I hope this helps. I've seen videos with really bad techniques of doing french tips. It irked me enough to make my own video. Lol
