Hey Kevin! I am in Chicagoland too and the ones mentioned are great.
If you get to Minneapolis, Glad Creations is nice and the Blue Bamboo is a real trip--online warehouse open to the public. Lollies in Shipshewanna is awesome.
My quilting GF doesnt fly so I dont get out of the WI/IL/IA/IN area too much. Been to some stores in San Antonio.
