I love Sauder's (a cousin to Zook's) it is in the basement of a home, and has lots of great fabric, and some bulk foods. I also love Burkholder's.
Sauder's is near Adamstown, and Burkholder's is between Adamstown and Middle Creek Wildlife management area.
If you want a tour guide when you are in PA, let me know... I would love to meet a new quilting friend!
