Step 4: Top part and visor
Cut a large circle, this circle will give your hat its size on the top, to measure according. Cut 2 of this circles, one will serve of that expansion the other as the main cover. Then using the cylinder trace the circle to be cut out of the visor part, draw another circle the same size as the top circles and draw the sides so that it has an oval shape you should end up with this.
NOTE: Use the circle and trace the pattern on the cloth that will be used to cover the hat, do the same with the visor, but trace it twice, one for the top part and one for the bottom. You should do this now because it will be very hard to do this once the hat is assembled.
