Here is a good source of SCWT grooming videos on YouTube. The owner of that account is Malc Jeffries, in case you want to search for yourself. Not sure, but I think they might be in Ireland. One indicator is the dogs’ tails are not cropped. Also there is an emphasis on grooming with scissors.
I’ve subscribed to Jeffries YouTube page as a future reference. Here is a sample video that I thought was good.
