You can use these alternative patterns http://snipriphooray.blogspot.com/2017/09/substitute-patterns.html . The middle on is free and the Voque ones go on sale every now and then.
Cut the pattern out and tape pieces together. Cut the fabric and lining on the fold. For lining I try to use a cotton blend knit, rayon knit or a performance fabric that will wick away moisture.
Stitch the seams marked with red.
Fold the hat in half so the rest of the seams meet.
Pin the top and stitch the seam.
Stitch the lining and main fabric together.
Stitch the lining to the main fabric at the crown with one or two stitches.
Handstitch the opening used for turning shut.
Press the top stitching and the hat hem.
To make the headband cut a rectangle 20 1/4'' x 5''. If your fabric allows wider than 5'' is better.
Pin the band right sides together and stitch.
Use the rolled hem setting on a serger to finish the raw edges. If you stretch the edge while serging then you'll get a curly lettuce edge.
Run a gathering stitch on the seam.
Gather tightly and knot the thread.
