Hi! Here I will describe how to make this 3D starfish on nail!
1) Start with nails prep
2) I covered the nail with a black gel polish and cured
3) Using a white gel polish I drew dots to portray pebbles. Cured
4) Here I added strokes with the mix of a top coat and a white gel polish. Cured
5) Using white 3D gel-paste I portrayed the base for my starfish and cured
6) I added one more layer of a white 3D gel-paste and cured
7) I added texture with 3D gel-paste. Cured
8) I painted my starfish with a red gel polish and cured
9) I added shades with the mix of a top coat and a black gel polish. Also I painted the bulging dots with a white gel polish and cured
10) I applied a top coat, cured and removed the sticky layer
3D Starfish nail design is done!
