Happylab your quilt turned out beautiful, love the quilting on it!
Rob, it is 3D, you use a double diamond ruler. They are a little tedious to make but I like the looks of it on some projects.
The quilt is the University of Wyoming fabric, batiks, for the Wyoming Cowboys. The 307 is Wyoming's area code. A guy was here picking up his quilt that h had me make, Royal Crown bags, and he saw this and bought it for his wife for Christmas. She went to the university and is a die-hard fan.
