The image to the right, from the Threads' site, is just one example of what is being offered. Check out how to make the bow for this hat, including how to make the faux feathers. When you're on the site query on millinery, hat making, hat trimming, and hat embellishment for even more millinery tutorials.
Please note that, in the sidebar to your right, there is a link to Threads noting to check out their stitch videos. Just query on your stitch of interest. Have fun!
