I have a friend who is making the wide brimmed summer hats out of cotton yarn. She thinks there is a teeny, tiny nylon cable that can be crocheted into the outer edge of the brim to make it stiffer.
You guys all seem so knowledgeable, I thought I’d ask here. Anybody know of anything like that?
Millinery wire will make it stiffer, all right; make sure that’s the kind of stiff you want – if you bend the edge, it’ll bend, for instance, and hold the bend. If you bend it back and forth too many times, it’ll break. I’ve worked with it rather a lot as both a costumer and for Irish dance costumes and bridal headpieces. It’s essentially wire wound around with thread, make sure you use the proper way to attach the ends into your hoop (you can wind the ends around each other, or try overlapping and winding your own thread around).
If all you want is to make it a bit stiffer, not so it will hold a shape, you can use a horsehair braid if you can hide it (not actual horsehair, these days), or use anything from thick monofilament (fishing wire) to tennis string (really).
I’ve often wandered the hardware store aisles thinking what would make good costume bits…I know, I know, getting a life is fun.

Plastic canvas might be an option to stiffen a hat brim.
With plastic, you have no worries about water causing rust.[/color]
