Here is this week's speculative fiction writing prompt. I'm not labeling it this week, so take it whatever direction you choose.
A spider in your backyard spins webs much stronger than any other material on Earth.
As always, feel free to use this in any way you choose. There's no need to give me any credit for any story you come up with. Of course, I never mind if you do give me credit for the writing prompt, but it's not necessary.
