Easily build a spider farm in Minecraft?

I'm more of a beginner and fascinated by fishing in Minecraft. But I need thread for that. And I don't have a village right now, so there's only spinning as a solution, right? How can I make a spider farm / bile? Or can I also win thread from wool?

The easiest way is to use a spawner from a mine shaft. You can easily convert it into a super spider farm.
