I spotted a really interesting asymmetrical bow in a reprint of an antique book on apparel trimming. It seemed like such a nice detail for a headband, hat, or even a well wrapped package. There were, of course, no directions on how to make it, so I spent some time working with different proportions and came up with this version (and included some measurements so you can make the same thing.)
