I always like doing nail art with specifique colors of a collection and I think the water marble technique is perfect for combining different colors in one design. I used my favorite polish from the OPI Nordic collection called My Dogsled Is A Hybrid as my base color for the marble. Then I added Do You Have This Color In Stock-holm? and Viking In A Vinter Vonderland to the mix. If you're unsure about this technique you can check out my Water Marble Basics.
