Clean your jar with mild soap and water or rubbing alcohol and let dry.
Start by spouncing white glass or multisurface paint onto the jar. Use a foam spouncer. Press the sponge into the paint, dab off the excess, and then press up and down onto the jar.You want to add a medium layer of paint. It is better to do multiple, thinner layers rather than one thick layer. Work one section of the jar at a time, layering the paint and covering the entire jar. Let dry completely.
Cut a 2" x 21" (approximate) piece of fabric or bandana. Fold in half and glue to secure.
Tie around the mason jar to act as a scarf. Tack down the ends with glue to secure. Your snowman doesn't want a straight scarf, so you can glue it down with a bit of "movement."
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 the end of your paintbrush and black acrylic paint to dot a mouth on the front. Let dry.
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..
