Yaffle:

Use a steam iron on low setting takes all the wrinkles and bends out of Duck and Goose quills that I use for wet fly tying. It also works nice on mallard flank that I use to tye Grizzly Kings and Professors with. Just a little insane smart input.

P.S. You can also repair a good amount of damaged quills buy steaming and shaping first and ironing second.
