I knit this cute hat for Nora last winter.

I told my sister, "It's 100% wool. You have to wash it cold, dry flat. Do you understand?"
"Yes," she said.
"So what do you do again?" I asked, testing her. "Wash hot, tumble dry low?"
"No," she replied. "Wash cold, dry flat."
She got it.
A few months went by and she called me. "You know that hat you made Nora? Can I wash it in hot water?"
"No," I said. "Wash cold, dry flat—otherwise it will shrink. Why?"
Silence.
And now some photos:




Apparently some kid in Nora's class got lice so she freaked out and washed everything in hot water, but still... WASH COLD, DRY FLAT!
Now I have to make a new one.
PS - I took these photos in March but just rediscovered and uploaded them today.
PPS - Nora didn't get lice.
