*****

Preheat oven to 350 degrees. 

Mix together butter, powdered sugar, vanilla and salt until well blended.  Add in flour then nuts. 

Roll dough into 1-inch balls.  Place about 1 inch apart on ungreased cookie sheet.

Bake for about 8 minutes.  Cookies are done when they are firm to the touch, but they will not be brown.  Make sure not to overbake them, otherwise they will fall apart.

Let cool for about 5 minutes, then roll in powdered sugar.  Let cool completely then roll in powdered sugar again.
