To make a snowman wreath, start by collecting enough snow to form three balls of different sizes. Once you have the snow, stack the three balls on top of each other, starting with the smallest and ending with the largest, and pack the snow together so they don't fall apart. Then, use twigs or branches to create arms and a face, using buttons or eyes made from berries or stones for the eyes. You can also add a scarf or hat made from fabric or felt.
