I've been hearing about it, and now that I've seen it, I think its pretty cool!!! Nail Marbling!
And better yet, the tool that helps you do it all is on sale for $3 at Sephora!
You can do the "dot and swirl" approach
dot the nails with color and use the tool to swirl and "marbleize" the color
or you can blend and marble in a bowl and dip in tips (then clean nails with remover)
To learn more about this trend, I scoped out this video by robin moses nail art (she is amazing!) and here is her "no water" marbling - a sneak peek at the end result
ANOTHER new trend in nails (and you're still prob trying to remove the caviar nails!) HA!
