I like to add a sheer Basecoat, I recommend white, if you want it opaque, add 2 coats :)
You can use a fine tip paint brush to draw the design. This design is almost a "connect the dot design, so it is very simple :)
Draw a line with a dot above the middle part of the line, you make the dots by gently pressing the fine tip of your paint brush on the nail or using a toothpick, or dotting tool.
Connect the line to the dot :)
Now place two dots above that, those two dots are going to determine the withe of the martini glass ( I'm sure you see the design coming together now)
Connect the vertical line diagonally towards the dots, then connect the corresponding dots with a horizontal line. There's your glass!
Place a small green dot on the bottom of the glass leaving a small space at the bottom because our pink pick is going to rest at the bottom of the glass, not the olive :)
Now take a Striper, if you do not have one use a fine paintbrush, and make a pink line from the top of the olive outward, then the space between the olive and the glass, place a small line or dot :)
You can add designs using a paintbrush, dotting tool, or toothpick or add rhinestones :) Add a topcoat to protect your design
