Mining Minecraft Spider Webs 1.8.9?

It was possible to scissors on the internet, but only dropped threads. Is there a way to break down or craft the nets?

Not in Vanilla. Only the threads drop.

Aua craften is certainly not synonymous?

No

When mining blocks with Silk Touch, they drop as block as it was. So you could break down with Silk Touch (pick or scissors with Silk Touch does not matter)

With silk touch scissors, thank you. But not with a pickaxe

With pleasure.
