Quiltinglady is right about the shop in Staunton. They have a nice big selection of both precuts and yardage, especially Moda. Here is the link to their Facebook page.:

An interesting summer attraction in Centralia is their Balloonfest in August. A three day event focused around hot-air balloons. Hope you have a great summer. Send me a message if you ever want to go shop hopping! :-)
