Here's one of my modern quilts which is called "somewhat reminiscent of a Japanese sunset" It's all hand-dyed fabric, machine pieced and appliqued, and then machine quilted. You can see all the lines that go across the quilt radiate from this point on the left side (detail above)
Here's a detail of a "hill". I composed this all on a felt wall while I pieced it, taking it up and down, over and over, making changes. For the longest time is was something I only turned vertically-and didn't even see the landscape, cloud, hill thing until I was almost done.
