Take a Glass container preferably which is having a plain surface without any texture.
Now with the help of black Puffy paint make squares and rectangles as close as possible to each other to get that Mosaic kind of effect and let the shapes dry completely before starting with the next step.
Now pick your favourite shades of Nail polishes to fill in all the shapes we made earlier. Now, look how colourful it will turn out. Let the polishes dry completely.
And this is the end result... So pretty and colourful!!
Now place a candle in your newly made Candle holder and get mesmerised by its effect...
