Why would having different coloured tools put you off of someone? The upgrades I got were recommended to me by a stylist at my daughters Grandads salon. All of the stylists that work there have different brands of tools and the girl in question had ones with flowers on. I think people are more interested in he skills you have than the colour/patterns.
I don't know if I've given the impression of a school leaver, but I'm 29 and not the oldest person on the course so I'm not sure why you think this class would only be for young people.
I think you are right about the block heads and I'd much rather work on models. I don't mind working on them to begin with but I certainly wouldn't feel happy to go out in to the workplace having only practiced on the block heads.
To be honest, my daughters Grandad has very high standards even when it comes to folding towels a certain way, so I imagine I will be made to do everything to a very high standard.
I would rather have done the NVQ but as my college only does the VRQ I'll have to make the best of it. X
