The construction of forms (solid crossword puzzles having simple geometric shapes) is a rapidly-vanishing art. I have been able to incorporate the names of nearly 40 states with their nicknames in the following collection of triangle and diamond forms. (The Art of the State would have been a more apt title, but this was earlier used by Darryl Francis.) Several of the less-familiar nicknames can be found in the American Thesaurus of Slang. Although many of the words look odd, all can be found in standard references (however, all citations have been omitted for brevity). Perhaps the two most interesting forms are the Montana-Louisiana-Connecticut-Massachusetts combination and the form uniting the Sunshine States of New Mexico and South Dakota.
