I like the "Walkin in a Pi Phi Wonderland" slogan.
Your ideas for decorations and scarves and the paper mache snowman are really good too.
You could serve hot chocolate and marshmallows!
Oooo cute idea!!! For the main table, you could make a gingerbread house for the centerpiece! And you can put snow (icing) on it and write your letters all over it!
