Query: Pseudo-Anosov homeomorphisms of punctured non-orientable surfaces with
  small stretch factor   We prove that in the non-orientable setting, the minimal stretch factor of a
pseudo-Anosov homeomorphism of a surface of genus $g$ with a fixed number of
punctures is asymptotically on the order of $\frac{1}{g}$. Our result adapts
the work of Yazdi to non-orientable surfaces. We include the details of
Thurston's theory of fibered faces for non-orientable 3-manifolds.
