I know Carlisle somewhat but not the quilting stores. I have a few suggestions though - if you have a smart phone there is a great app I have called "QUILT SHOPS" that uses where you are and then maps out quilt shops within a specified area (ie. 20 miles from where you are).
My next suggestion is - you are only an hour away from BIRD IN HAND, PA - this is one of the nicest places to visit for quilters there are several stores that sell quilts and several fabric type stores either in BIH or near there - this is considered Amish country (At least I always considered it part of Lancaster Amish country). And you're only a 1/2 hour from Gettysburg, PA I believe there is a nice quilting shop there PLUS it is an awesome place to see. And don't forget Harrisburg, PA there are (If I remember correctly) 2 nice quilt shops there. You're about 45 mins from Hershey PA which has a nice quilt shop - AND it is a neat place to see.
Don't know if this helps but maybe it will give you some ideas?
Good luck and have fun.
