Use wire cutters to clip off the arms or bend the wire arm sections until they pop off.
Cut the mop pad into sections -- 3 sections will make fluffier snowman, 4 sections will fit the frame more narrowly.
Place the cloth mop pad fluffy side down on your work surface, then place the wreath form on top. Using plenty of hot glue, attach one section of the mop pad to the front of the wreath, wrapping the entire front of the frame and the edges with the fluffy microfiber cloth. (You can see what it looks like here from the back.)
Repeat this process around the entire lower section of the snowman wreath form.
Continue gluing the mop pad to the upper circle section of the wreath form until it is completely covered.
Cut a piece of faux leather/fur/felt a little bit larger than the square part of the hat.
Glue the square of material to the front of the hat, then wrap it around the edges of the hat section and secure the excess to the back.
Cut a piece of material the width of the wire wreath form hat brim and a couple of inches long. Roll this piece of the hat material into thirds and hot glue to secure in place, covering the wire on the bottom of the hat.
Tie the scarf around the neck section and trim the end as needed.
Hang the snowman wreath on a hook or wreath hanger.
