Hi Marian I used an 8 inch hoop, and the cheese was around 2 inches thick. Personally I would have preferred about a 6-7 inch hoop, but I don't have one.
The recipe didn't ellaborate as to how often to apply the rub, etc. I have brined this cheese, put it in a port bath, and also accidently got some white mould on it, and waxed it. All give a different flavour, but my favourite was to just brine and age for a couple of months. HTH
