Now this is only my second install so bear with me. I have laid my nail down bamboo up and out toward a pony wall. Now I need to go around the wall and back toward my starting row. I am laying probably 15 rows back so I hope there is a alternate to nailing the face of the boards.

Sounds like you are switching direction and need to nail the tongue side? If so, you need a spline to create a tongue, nail it like a regular board and carry on.
Your supplier may have spline stock, if not, you need to make your own on the table saw.

Sounds to me like they need to continue off the starting row, on the other side of the pony wall to meet up and continue the installation, in the same direction.

Is this tying back into the starting row?
