Down the street and across from Old Country Store is Zooks. Go there. They are a fabric store as well. They are the sister store to Sauder's. Also, for DH and the kids, Straussburg has an antique train museum and you can take a train ride. In Straussburg is another Zooks. They have crafts and antiques, but also a cute fabric section with quite reasonable prices. That store might interest DH since they don't use electric lights or fans. Out on 30 by Kings and Diener's restaurant is a store that has their fabric section upstairs. They have a nice supply of fat quarters and a sale room in the back.
Further down from the Fabric Shack in Bird-in-Hand is the Log Cabin, and further still on the other side of the road is Sylvia Petershiems. Sylvia's doesn't have a lot of fabric in her shop, but if you can convince them to show you the inside of the barn/garage, you've hit the jackpot. It's normally only open during the quilt show, but I think she will let people in once in a while otherwise.
Near Shady Maple and Goods (and Obie's) is a newer place, but I can't remember exactly where it's at. I think the name is Farm Family or something like that. It's a lovely shop and the owner is delightful.
Those are the other shops I can think of. I love, love, love getting away to Lancaster. Have fun!
