Cream butter with the 1/2 cup of powdered sugar. Add vanilla. Combine flour, pecans and salt. Then add flour mixture to butter mixture, form dough, and refrigerate for at least 1 hour. Shape dough into 1 inch balls. Place on ungreased baking sheet. Bake in 325 degree (F) oven 20 to 25 minutes until lightly browned. Roll warm cookies in powdered sugar. Cook on wire racks; then roll cookies again in powdered sugar. Sprinkle with additional chopped pecans, if desired.
