"Nothing says unprofessional like wrinkles in the duct tape." -- RecklessPrudence
Of all the useful concepts and handy inventions that the humans took into space with them, the most widely-dispersed was ductape. It even preceded dogs as an ambassador for humanity. A watertight adhesive patch that could be shaped to suit the user's needs. Cut to demand. Flexible. And infinitely useful.
After a few hundred years, standards for its use grew. Including the quality of the user based on how ze applied it.
"A true professional leaves no wrinkles in the ductape," dictated Dode, his tutor. "Take it slowly. Carefully. You'll get faster with time."
