Hermione Sweater for Harry Potter 5

So, I am in a knitting mood, particularly recreating things from Harry Potter movies and while I am working on my hat, scarf and gloves from the sixth movie, I decided to try my hand at a sweater…But i can’t find a pattern.

I found the Fair Isle chart, but now I need a sweater pattern. I would prefer to find one I can knit on size 8 needles so that i can buy fewer skeins of yarn (I have a sweater pattern but it’s on Size 5…I can use it if necessary).

Does anyone know where I can get a sweater pattern in Size 8 needles? The collar is K1 P1 ribbing and the waist is K2 P2. Here’s a picture:

These are the only free ones I could find right away. Your needle size is so specific it’s going to be hard to do, but these might work.
