The Quilt Patch in Tecumseh is wonderful. I haven't been to the one in Marshall yet,but it's on my list. There's a Viking Sewing Center in Ann Arbor that is very nice.
Wyandotte has 2 quilt shops 1)Sew Fun & 2) Sew What & Trenton (not far from Wyandotte) has one called Pieceful Traditions.
Good Luck
