  In this note we establish a density result for certain stationary shear
flows, $\mu(y)$, that vanish at the boundaries of a horizontal channel. We
construct stationary solutions to 2D Navier-Stokes that are $\epsilon$-close in
$L^\infty$ to the given shear flow. Our construction is based on a coercivity
estimate for the Rayleigh operator, $R[v]$, which is based on a decomposition
made possible by the vanishing of $\mu$ at the boundaries.
