Moda got back to me and said they can't find a collection by the name of "Cardinal Season" yet their PDF for Cardinal Reflections says Cardinal Season is one of their best selling lines and made it sound like the Reflections is flannel based on the Cardinal Season. If I didn't already have two pieces of fabric from the Cardinal Season line I would believe it never existed. Another possibility is that it's from the North Woods Botanical collection but I can't find anything on that one either. Maybe it's because they are both so old. It was probably 6 or 8 years ago when I bought these as a packet of 6 or so half yards bundled together at my LQS. So strange.
