Undulating 2-line Extended Manifold Twill

I developed this draft for the interleaved twills class that I teach.  Two different twill lines starting on shafts 4 and 8 are extended to 434 and 87.  The two twill lines then progress to 323 and 76, 212 and 65, and so on.  The treadling is straight draw, one shot per pattern shed , followed by two shots and then 3 shots and 4 shots before reversing back.  Pattern shots alternate with pseudo-tabby shots on 1247 and 3568.  The increasing pattern shots per shed create undulation.
