I don't know what that means either, but I made a slouch hat and it's darn cute, on a potato or otherwise.

It's made from a really soft, light gray blend, fuzzy, but not at all itchy.......
.....hee hee, she looks cranky about it, but she's not, she was just tired of modeling for me.
I will be listing my hats in the shop starting tomorrow, I will have this one for kids and grown-ups, but not potatoes.
