This pattern is written for a large-sized hat with 116 stitches. If that is too big for your head, you can cast on 96 stitches instead and follow the pattern as written (note your stitch count for the decreases will not be the same).

I used less than a quarter skein of each yarn, and I ended up being 8 stitches short in my pink colour. You need at least 20 g of the stripe colour and 26 g of the main colour.
