In a mixing bowl, combine softened cream cheese, shredded cheddar, crumbled feta, green onions, garlic powder, and onion powder.

Using a spatula or your hands, mix well until everything is well blended.

Divide the mixture into three portions: one larger for the body and two smaller for the head and middle.

Roll the portions into balls to create a snowman shape.

Wrap each cheese ball in plastic wrap and refrigerate for at least 1 hour.

On a serving platter, stack the cheese balls to form a snowman.

Decorate with baby carrots for the nose, pretzel sticks for arms, and olives for eyes.

Arrange assorted crackers around the snowman for serving.
