So I'm doing test spins currently, trying to get a feel for the different fibres that come in question (all of them compromises, because of the lack of real Bronze Age type sheep with their very special type of fibres) and getting a feel for the thicknesses and twist levels that should be suitable. Once the test skeins are done, they get a bath:
and then they are hung up to dry.
Afterwards, I weigh them, label them, calculate the Nm value (that is purely out of curiosity, though), document how long it took me to do that amount of yarn, and once the last batch will have gone through this, weaving tests can start.
It's always fascinating to see how different types of wool spin out differently, and have different properties afterwards (like the Nm count) - even if the yarns have about the same thickness and the same amount of twist.
