I’ve seen quite a few nail designs using straws, I experimented, but with a small coffee straw.
Start with a base coat.
Then, cut the straw down for accuracy, and blob some nail polish onto a piece of paper.
Dip the straw into the nail polish, then touch the straw to your nail, dipping your straw every couple circles. Do not worry if you do not have a complete circle. (I do not know why this picture ended up so purple, sorry.)
When the first layer of circles have dried, add another layer, this time start around halfway and continue to the end of your nail.
Add a third and final layer at the tip of the nail, let it dry, clean up, and add a topcoat!
I used Siren by Revlon and Hit the Brakes By Spoiled (by Wet n Wild).
