Make a house with box, cardboard and tape. Cut windows and tape cellophane inside. Cut door. Cardboard is for the roof. Tape securely to large tray or board.

Frosting: 
Beat sugar, egg whites and vinegar until stiff and glossy. Spread frosting over roof and make shingles with graham crackers. Spread outside walls, one at a time, with frosting and decorate with cookies and candies. 
Spread frosting on ground around house (this covers the tape that secures the house to the tray). Make snowman with marshmallows. Make walkway. Make pine trees with green gumdrops of descending sizes. Let your imagination go wild!

*Note: Size of the house will determine how much frosting, candy and cookies are needed. 
This frosting dries like cement. So the house is secure from little fingers! It dries fast also.
