(left) Combining an open bundle (in black) and a closed bundle (in blue) by exchanging half paths. Dots represent free ends, rectangular blocks represent T vertices in half paths. Cuttable edge in red. This may be iterated to incorporate more closed bundles in a linear or circular structure as in the large open bundle on the right. Cuttable edge is in original open bundle.
