You just clarified something I’ve unknowingly wondered about for years! Hardware stores here sell duct tape as you describe it, but it’s commonly referred to as «gaffer tape» in my native tongue (Norwegian: gaffateip). I’ve never come across the cloth tape you describe, but I now realise it’s not a skill issue when I can never seem to tear clean strips of the stuff. I’ll keep my eyes open for proper «gaffer's tape» from now on.
