Quite a few shops have closed down in the Milwaukee area. Patched Works is in Elm Grove (off I41/45), Quilted Basket is in Menomonie Falls (off I41/45). Quiltropolis is in Chicago proper, Vogue Fabrics (mostly fashion - some quilt fabrics, fabulous prices) is in Evanston, IL. There are more in the Chicago suburbs but I have not been able to find them. If you are driving North on I41 through Menasha then Appleton: Primitive Gatherings is in Menasha, Appleton has Sew n' Sew on N. Silverspring Dr. If you are traveling North on I43 (along the lakeshore)towards Appleton, Cedarburg has several and it is a unique town. There are several in Green Bay (north of Appleton). There are several in the Madison/Wisconsin Dells area but this is in the middle of the state. There may be others that I do not know about (yet)
Hope this helps. Terri
