I'm cool with "scrappy" for a descriptive term.
Once upon a time, when people actually used their clothes until they wore out, quilts were made with the scraps from that clothing that were still usable. Today we use the scraps from other quiltmaking. (Tho, I have made many beautiful quilts from old shirts.) These scraps are new fabric and cost just as much per yard as new yardage... so 'scrappy' is not a derogatory term, to me.
