The Singular Pantyhose

On the ride home from school yesterday, I was taught an interesting grammar lesson:

Me: What did you do in school today?

OG: We made spiders out of pantyhose in art class.

Me: Oh, that sounds cool . . . How do you make them?

OG: Well, first you take a small piece of black pantyho and then . . .

Me: Wait, what do you take a piece of?

OG: You take a small piece of black pantyho. You don't need the whole pantyhose, you just need one piece, so that would be a pantyho.

Me: Yup, that's about what I thought a pantyho might be . . .
