I absolutely love Connies in Marion. :D It's in an old house and very cramped but tons of really nice fabrics there. Cottage Rose in Marion is really wonderful also....
There is, if you will be traveling I-80 or going to be near Leclaire Iowa..on the way to Cedar Rapids...a really nice shop in Leclaire. I'm sorry that I can't remember the name of it right now, but I know from Mom and Sis in law that they have a website and are really great to deal with.
P.S. I'm only about 45 minutes away from Cedar Rapids :D
Hugs and have a safe trip.
Also, you should take the time to go to the Amana's. THere is a really awesome shop called Heritage Quilt shop in an old renovated barn.
Again...be safe and have lots of fun :D Tigger :D
