You see the white snowflake section, this is what the chart refers to. It seems you will repeat the chart all the way around the circumference of the hat.
So, your next row will be K2, row 1 of chart, K2,K2 row 1 of chart, K2,K2row 1 of chart… and so on all the way across until it ends with a K2.
Continue to follow the rest of the chart and then you carry on in stocking stitch using the main colour as before.
Good luck with your project and please show us a photo when you finish it
ETA: probably best if you remove the photo of the written pattern because of copyright issues.
