You can use any base coat you want. I used "Shocking Pink," also by China Glaze. (Sorry for the bad quality pic, taken by my IPhone.) Make sure that the base polish is completely dry before adding the "Crackle" polish. I used "Black Mesh." The amount of crackle polish you use will affect the finish look. The thicker the coat the larger the effect. I use medium thick coat on mine and I love the finish look. Make sure to finish the look with a top coat to seal the design.
