No, actually that's 7-7-7-6, unless 'now i will try a haiku' wasn't your first line, in which case you still have 7-7-~6 which isn't 5-7-5 either.
Let's try this:
Have now: a haiku
Luna caught: a spider's web.
Not silk; rather, rope.
Silk is fabric, as is cotton, btw. Nylon, kevlar, anything that can be made into strings and then woven together into a flat, malleable flap of material can be called a fabric.
Storage area networks only call themselves a fabric; I don't believe I've ever seen their network cords properly woven to be called a "fabric" they just are dispersed enough that, with some work, you could make a weave.
You can weave those cords (cotton, silk, steel, network, etc) into a rope instead, and because it's long, skinny, and used to hoist things instead of cover them, rope is not a fabric.
If you use fabric to make a rope, such as hanging yourself with a bedsheet the grammarians break out into boisterous infighting
Not that that's relevant, since Epstein didn't hang himself
