Maria--Here is a link to the quilt shops in the area. Most are Amish. All you have to do is click on the number on the map and it wil give you directions to any of the stores. Most of them do not have a web site, but if you went to the store some of them may offer classes. I lived in the area for a year and the quilting opportunities there are fabulous!! (Also a great place to start-or add to-your stash!!)
