I first drew the design I wanted to create on paper. Drawing and painting on a bottle can be tricky so having a rough version of what I wanted to achieve on paper made it easier for me.
I then used the black thin Posca Pen to draw my outline on the bottle. This was tricky but I managed to do it okay.
Next, I added the white followed by the red and for the Penguins Santa hat. if I made a mistake I could quickly wipe it clean using a piece of toilet paper before the paint dried. It does fry pretty quickly so any mistakes need to be dealt with immediately.
I then filled in the penguin's body using a thick black Posca Pen and then added the yellow for the beak and feet.
