DIY Retrotastic Camera Bag Material and Pattern by Berene Campbell. From Spoonflower (the create your own fabric site I absolutely love) here. More details at link. You will need to buy a fat quarter of upholstery weight cotton twill that is $17 and you get a bonus mini camera key fob out of it. I love these cut out and sew fabrics.
