All you need for this project is a few bottles, depending on how many milk bottles you want to paint and a mix of thin and thick tipped posca pens..
First, you draw the outline of the snowman. I’d recommend using a white posca pens for the outline. This makes it easy to see.
Add detail, a scarf, buttons, and any other detailing to your snowman image.
Next, use a black paint pen to create a hat. You can paint a black cap or choose another colour to decorate the hat. I added some red and a yellow buckle to add character to my hat.
Next fill in the parts of the scarf. I went for a red and blue scarf. Again you can choose whatever colours you prefer.
Add the detail using a thin posca pen, colour in the buttons, add a mouth and eyes and an orange nose. Finally colour in the white with a thick white paint pen.
