Below is a link to many quilt and fabric shops in the area. I have been to many of them. Zooks and Old Country store are across the street from each other in Intercourse and there are other types of shops in the same area of Intercouse. Plenty of parking there, too.

You might enjoy eating at Millers on the east side of town. It's a very complete buffet and the food is very good including many Pennsylvania Dutch dishes.
There is a small museum in Lititz which is in the area. Link to Lititz guide:

There are also outlet stores, two sets of them on Lincoln Highway. If you go that way to Millers, which is further out of town on the same road, you will pass them.
I'm sure others will mention other things you should see.
