The Modern Quilt Guild that I was part of for a while had a lot of informal rules as to what was modern. One of them seemed to be to use only fabrics from one of the "Modern fabric designers" I think the origin of the modern quilting movement was to make simple quilts with lots of background and a few large differently placed piecing objects in it using what you had on hand. Also low volume and also using non-traditional colors then what is usually taught in a color theory class. Also simple quilting, none of the fancy feather things. Anyway, I went back to using my fabric stash with the occasional new fabric purchase. all the rules as to what made a "Modern Quilt" in that group just got to me. I thought they were trying to be Modern quilt police! Wasn't the Gee'sBend quilts the inspiration for the Modern Quilt movement?
