I vote for all of the above plus I would add Quilt Fabrics, 75th street/Rte 83 off of Interstate 55, in Willowbrook if she really likes batiks. Which is probably 40 minutes away but has the best selection of batiks in Chicagoland, IMHO. In Chicagoland, we measure travel in time not miles....my sister lives near Aurora and I am 53 miles away but it can take up to two hours to get to my house.
I really dont think Aurora has a quilt shop. You cant go across the town of Aurora in 10 miles. Aurora and Naperville are like Scottsdale and Mesa. They have a combined population of probably 300,000 people and are a major corporate hub.
