I am an avid SB fan but think people forget it’s a TV programme as well as a sewing challenge. Personally, I would find watching somebody mend something really dull. If I want to see that, I can look on YouTube. I can appreciate the skills involved but it’s not exciting TV for the casual viewer.
I don’t think anyone expects the transformation challenge to be that wearable, but they do like to see the ingenuity and imagination on show. The possibility of disaster is also a an appeal of this challenge if it was all about sewing there wouldn’t be a time limit on any of the challenges. The rush around not finishing and the edits showing chaos are what keeps the programme alive.
There may be a space for a more conventional sewing programme demonstrating skills, but this isn’t it
