HMMMM If they sent the wrong color I would....call inform them of the mistake, inform them that you can't hardly finish your half way done quilt with the fabric they sent you and that you would like to A) return the fabric for the right stuff (if this is what you are wanting to do) or B) come purchase the right color fabric, either way before driving up there make sure they HAVE the right color. They could have simply sent you the wrong color by mistake or they MIGHT have been out of the color you needed and found the next best thing. Kindly inform them you are calling to find out if they have it before you drive 120 miles round trip to get what you ordered. IF they value their customers you might get something for your time!
If they are not willing to do anything about their mistake I would chalk it up and find something else but I don't know that I would any longer be a customer in their store!
