Possibly a Jinny Beyer fabric
Iceblossum: I uploaded a photo of a close-up of a quilt I made that included a fabric in a pink color way made up of striped mini hexagons, which I think was designed by Jinny Beyer in the 1990s. You have the grey color way of that fabric in your border for Grassy Creek.
I must have been a big fan of Jinny Beyer designed fabric back in the day 'cuz I used a blue fabric she designed in my Grassy Creek and then saw it show up in Bonnie Hunter's Rivanna scrap quilt she just finished.
