  Minimal surfaces can be though as a mathematical generalisation of surfaces
formed by soap films. We consider Bour's minimal surfaces $\mathcal{B}_m$ that
are intrinsically surfaces of revolution. We show how to generate crochet
patterns for $\mathcal{B}_m$ surfaces using basic trigonometric identities to
calculate required arc lengths. Three special cases of $\mathcal{B}_m$ surfaces
are considered in more detail, namely Enneper's, Richmond's, and Bour's
$\mathcal{B}_3$ surfaces, and we provide exact crochet instructions for the
classical Enneper's surface.
