I usually ask myself does the outer border need to stand on its own or does the binding need to bring it all together? Sometimes the outer border will be bold either in color or motif so the binding can rein it in. If the border is soft in color or motif the binding just needs to finish the edge without drawing any attention. All these statements are only MHO.
Sometimes I equate it to coloring a picture in a coloring book. Sometimes you would outline everything in black or use a color in a darker shade to outline (make sense?).
