  In single-flavor QCD, the low energy description of baryons as Skyrmions is
not available. In this case, it has been proposed by Komargodski that baryons
can be viewed as kinds of charged quantum Hall droplets, or "sheets". In this
paper we propose a string theory description of the sheets in single-flavor
holographic QCD, focusing on the Witten-Sakai-Sugimoto model. The sheets have a
"hard" gluonic core, described by D6-branes, and a "soft" mesonic shell, dual
to non-trivial D8-brane gauge field configurations. We first provide the
description of an infinitely extended sheet with massless or moderately massive
quarks. Then, we construct a semi-infinite sheet ending on a one-dimensional
boundary, a "vortex string". The holographic description allows for the precise
calculation of sheet observables. In particular, we compute the tension and
thickness of the sheet and the vortex string, and provide their four
dimensional effective actions.
