Indianapolis:
Quilts Plus, north side on 86th Street Huge selection
Quilt Quarters, north side just off 86th north on Michigan, wonderful modern and new fabrics again huge selection.
Back Door Quilts, 40 years old this month, civil war, batiks, wonderful crafts. On south side. Somewhat difficult to find, call for directions. There are two more between Indy and Noblesville. Always in Stitches and Quilt Expressions. Doable in one day with the others on the north side.
Downtown on Massachusetts Ave. is a new little shop called Crimson Tate with modern quilt fabrics and a great staff.
Indy would be a great shop hop all by itself.
