Mix just a small amount of cornstarch to your polish to make it matte. Apply quickly or else it will start to get clumpy. It may feel like it applies weird and clumpy but as it dries it will smooth itself out. (tip: the more cornstarch the more matte it will turn out!) enjoy!!!
mix a lil paint with a larger amount of water then place drops on your nails ,let dry just long enough for the edge to dry then with a dry brush or a q-tip place it in the center of the water to absorb the excess amount and you should be left with a bubble like effect
