Super-Weaving. Yes, this is a thing. You would think this is just Superman using his super speed to weave really fast. Instead, this is somehow its own specific power that he actually used. What did he use it for? Making a wedding dress.
It's hard to imagine a situation that would come up that would allow Superman to find out he even had this ability. Seriously, how did he find out he could do this? Why did it come up? The one time it does get used is Superman's Girl Friend, Lois Lane #15. Technically, it was his cousin Van-Zee who showed the skill off but they are both Kryptonian so super-weaving is in Superman's super-pocket, too.
It's kind of strange that it's super-weaving and not super-sewing.
Also, you can't help but wonder if he can only weave dresses, which is an odd thing to weave in the first place. It's possible that he could weave a wonderful throw rug that would really tie the room together.
