I didn't know if I could pull it off, but the pirate hat is done. Now, I just have to make the rest of the costume.
Crochet BeanieUse geometry to figure out size of doughnut hole to cut out of faux leather. I admit, my calculations were a little faulty--you'll see the back section folded over on itself, but whatever.Cut same shape out of cheesey stiff fabric that no one will really see to help it hold its shape. It turns out you can see it a little bit--but, again, whatever. Sew these two pieces together. I just laid one on top of the other and top stitched once around the inside circle and once around the outside.
Sew the edge of the hat to the inside circle--a little bit tricky getting the bulky crochet under the sewing machine foot, but it worked.Pin together the three points and stitch just enough to hold it in place.
And Voila! This boy will make a smashing pirate come Halloween.
