How To Overseed Fescue Lawn

Question From: M. Warner - TENNESSEE
Q: Nancy...I have recently built a new house. The landscaper sowed fescue around November of 2012 with a starter fertilizer and covered the new seed with a thick layer of straw. I am currently seeing some new grass popping through the straw. I want to overseed the lawn this spring with a dense spreading of fescue. What is the best way to do this? I live in upper East Tennessee (Zone 7....I think.)
