Sewing "a little bit" is one of the most useful skills you can possibly have proportional to how cheap and easy it is to learn.

ALT for above: screenshots from a paper entitled Surfaces with Klein bottle topology occur in fusion reactor fields. Text: This paper does not solve any key problems on the path to realizing fusion, nor does it claim that its conclusions are important. It exists purely because of the aesthetically pleasing nature of the novel observations it contains, highlighting profound connections between pure mathematics, applied mathematics, and physics. It has often been lamented by plasma physicists that if only we lived in a universe with four spatial dimensions, fusion would be easy to solve. Footnote: This lamentation comes mostly from myself, though I have seen S. R. Hudson nod bemusedly when discussing this with him.
