Heart Strings and Angel Wings is a nonprofit group that sews clothes and other items for premature babies and donates the clothes to Neonatal Intensive Care Units in local hospitals and parents of premature babies.  Sigma has been a sponsor of the annual fund raiser for the past three years, with the proceeds going to buy the material used to make the clothes.  Sigma Employee, Dale Knott, has been participating for the past 6 years.  This event not only supports a great cause but is a lot of fun!
