At first I thought it was 2 duplicate quilts sewn together (back to back) - shows how little I know! Now I realize the triangles on the back exactly match those on the front, so the quilter obviously took a "square", folded it in half diagonally, then stitched it to others in a whole row, then attached it to a whole row of white triangles, then another row of print triangles, etc. to make a double sided quilt that matches the front.
