Ok thanks for the link. For the hat
the cast on is 9sts for the earflaps and row 1 works those 9sts. Don't multiply the number of sts in row 1 by 2. The pattern is for double knitting
which is shown in the video from the top of this page, Advanced Techniques. I think the notes before your pattern are worth reading and it's worth clicking on the link to the article in Knitty as well.
Row 3 has the 4 increases to 13sts.
Should work out to be a very warm hat, great for snowboarding or just shoveling the stuff!
