In Indiana, Yoder's and Lolly's in Shipshewana are the BEST! Plus, it's Amish country and you can get great foods and crafts there in town. I make a quarterly trek down there from Michigan, even if it's just to pet the fabrics. In Columbus, the Glass Thimble is great - in an old house, and rooms and rooms of fabric
. Red Rooster Quilt Shop is also very nice. If you like more contemporary quilt fabrics, Quilt Trends in Worthington is great. They also carry a large selection of Kaffe Fassett fabrics.
