Results are given from a density matrix renormalization group study of pairing on a striped t-t'-J lattice in the presence of boundary magnetic and pair fields. We find that pairing on a stripe depends sensitively on both J/t and t'/t. In the strong-pairing model-parameter regime the stripes are easily coupled by the pair field, and have a uniform phase. There is a small but measurable energy cost to create anti-phase superconducting domain walls.
