There is a relatively new shop, The Farm Family Quilt Shop, I think it's called. It is at the intersection of Rt. 322 and Rt. 23. I think the town is Blue Ball. One of my favorites is the Quilt Ledger off Rt. 41 in Christiana, PA. It's about 25 minutes from downtown Lancaster. She has a great eye for fabric.
If you don't mind traveling a bit, there is Ladyfingers in Berks County. The owner designs for Andover, so has great prices on Andover fabrics.
Both the Quilt Ledger and Ladyfingers have websites. So you can check them out online and get directions.
Have a great time!
