So, one stroke painting is a bit harder than I thought. Everyone makes it look so easy! I tried a really simple one to begin with. Perhaps its the size of the nail that makes it hard, i was doing decent on paper. Anyway here it is. Sorry its so picture heavy, it was a hard nail to capture. The base coat is OPI Not Like the movies, and then i used random acrylic paints. The book is The Brushstroke Handbook by Maureen McNaughton.
Hope you enjoy!
