A brownie's hat needs 7 skeins to grow up stout and sure.
A witch's hat eats two times that, as does a warlock's tur.
A stately fez eats modestly, but 4 or 5 skeins full.
A dread-locked dome, the madman's home, sups but snips of wool.
A tangle of the ewe's coat falls and twirls betwixt the pins,
And hatters full a rainbow mound to sidhe-helms for their kin.
Olwyn has a spirally felt hat. I wasn't sure who it was for until I saw her at Sheep and Wool. It fits well. Good thing she has a thick wool felt hat in time for summer.
I will find evidence of her inclusion in this shadowy organization soon.
