Cut a piece of white tissue paper into squares using the scissors. You're going to apply this to the mason jar so make sure the pieces aren't too big.
Working one section at a time, apply a layer of Mod Podge to the mason jar. Place the white tissue paper down and brush over the top to secure.
Repeat this step until the entire jar is covered. Lightly smooth the tissue with your fingers and let dry.
Apply a top coat of Mod Podge over the entire jar and let dry.
Cut a 2" x 21" (approximate) piece of fabric or bandana.
Fold this 2" piece in half and smooth with your fingers. If it's not cooperating, you can also iron to make it flat. Tack the scarf to itself to keep it folded with some craft glue. Let dry.
Wrap the scarf around you snowman as shown. Use the craft glue to tack the bottom pieces of the scarf to the jar. You might need to hold for several seconds until it stays. Let dry.
Glue two large black buttons to the front under the scarf. Let dry.
Glue two small black buttons to the front above the scarf to act as eyes. Let dry.
Cut a nose from orange craft foam or felt and attach to the front with glue. Let dry.
Use your paintbrush end and black acrylic paint to make dots for the mouth on the face. It helps to start in the middle and work outwards so everything is properly placed.
Trace a circular object larger than the lid onto the craft foam or felt and cut out.
Trace the jar lid onto the center of your new circle and cut out.
Place the brim you just created onto the mason jar and screw the lid on top to finish.

Notes
Be careful not to brush too hard or too many times over the tissue paper. As the Mod Podge saturates the tissue, it will make it wet and easier to tear, so be careful.
