Landscape collaborative quilt
Rob, big time congratulations. This is the 2nd ribbon I know of that you and your partner have earned on this quilt and well deserved at that! It is no small achievement to ribbon at an AQS show. Take a bow! And I am sure he appreciates that someone at the show was able to post a pic of his quilt so beautifully adorned with a well deserved rosette! Edited to add that I am so glad the show had such great lighting to show off this beauty.
