The one valid reason I know to roll your own is to make something that
sits nice and flat under a carpet. The commercial offerings all seem to
be horribly expensive. I have in the past made a speaker cable from two
layers of self adhesive copper tape either side of some polythene. Even
under a very thin mat, they couldn't be felt.

Being lazy I'd tend to use the 'flat' cables from someone like Maplin.
However the construction you describe is potentally a very good one from
the POV of having very low series inductance. (The snag being high shunt
capacitance, making it unsuitable for some amps - which I would not use
anyway! :-) )

Slainte,
