Well some of you may have "Bill's Favorites" or "Nancy's Favorites" but I believe I am the only one to lay claim to a set of "I.O.'s favorites"! He made a set out of left over pieces of balsa wood. "Bill's" are strung on a piece of goldish yellow cording and strung across the front of the top shelf of a barrister bookcase that has HL's in it. "I.O.'s" are on a shelf of HL's.
