Oh, that would be cool! I don't have any idea what sort of patterns would use cording, but I'm willing to figure it out! At first glance it looks like a hat, the style with earflaps would use cording.

Or! Oh, you could make a set of bracelets, and I can include them in the charity package (it goes to teens in the foster care system and homeless teens in SF so having just something neat that lets them know someone's thinking about them is awesome.) Like with some gender-neutral beading, even.
