Hi there! This is a nail art design that I did last year (you can find the post HERE) But I got a comment about the fact that there's no tutorial, so I made one! I haven't been doing tutorials before... Sometimes I've just explained briefly what I've done but here we go! I hope this helps!!
1. Paint the whole nails in one color. Then make big dots in another color. They don't need to be perfect circles!
2. Then make three a little bit irregular lines around the dot and one half-moon or something similar in the middle using e.g. a nail art brush.
3. Make green leaves, and again, they don't need to be regular! You can just make really small stripes around the rose.
