Snowman gauge is not important. Finished size depends on yarn and hook size you use.
I used bulky yarn size 5 with a K crochet hook.
My finished snowman was about 9 inches high and
4 1/2 inches wide.
Pattern is done in the round without joining unless stated to.
The pattern for the hat and scarf are included in pattern.
Items needed are 2 different colors of yarn that are
the same size which will be for the body and hat.
Scarf yarn size does not matter.
