I think your fabric is gorgeous. If it were mine, I think I might use it in a "Sashiko with Applique" quilt design. Since it appears to be a big print, you might want to save some of it to use in the border. I couldn't refer you to a particular website, but you can see an example of a Sashiko block that I made on the second personal photo on my profile.
If you like, e-mail me through my profile and I will forward to you a copy of the instructions that I prepared for my quilt guild when this was the optional block and I was the Optional Block Chairperson. These instructions include a lot of sashiko ideas.
Also, I suggest that you browse the web for images of Sashiko and other Asian quilts.
Please keep us posted when you decide what to do with this fabric.
