I have to say I love these little swishy nails. I want to swish them around and see how the light catches the sparkle in the green polish.
Not to difficult to create, the hardest part is getting enough polish on your nail to swirl but not too much that it drips all over your finger. Start by painting half your nail a light colour and the other half a darker colour. Then quickly swish a dotter tool or pointed bamboo stick around where the two colours meet before it dries. It’s maybe easier to do this with shellac as it doesn’t set without curing but it’ll work with normal nail varnish so long as your quick.
