Click and hold on the snow to make snowballs. The longer you hold down the mouse the bigger it gets. Make 3 different sized balls. Then move the snowballs into position. Once the balls are set up, press the "decorate" button that will pop up. Once you press "decorate" you will not be able to move the snowballs anymore. A hat, eyes, nose, mouth, scarf, and buttons will come up. Drag them onto the snowman. Click them to change how they look (each accessory has 3 or 4 options). To enlarge or reduce, put the cursor on the accessory and press the up or down arrow on your keyboard. Enjoy! Take a screenshot when you're done!
