Don't know the routes you'll be taking from Uniontown to K-zoo, but there is an absolutely unbelievable quilt store called The Door Mouse in the tiny town of Bettsville, Ohio on route 12. It's in a barn and it is LOADED with fabrics! Very well organized and managed. I try to get over that way at least twice in the winter, but it sure puts a crunch in my credit card! It's just west and south of Fremont. And also in Bettsville is a "diner" that makes the best homemade pies ever.... yummm.
And then of course, if you take the turnpike, you could stop at Shipshewana, but not on Sunday.
