Big Tokyo Weekend Quilt Show #8 Just Quilts

I told you at the beginning that I took about a million pictures.  I wasn't kidding.

Big Tokyo Weekend - Quilt Show #7 Wa Quilts

I'm not sure what the rules are to be included in the "Wa" category, but I think it is using either Japanese fabrics, Japanese subject matter, or Japanese techniques in the quilt.  Can anyone tell me if that is true? These were my favorites in the show.
