I used a Blue Sky Woolstok 50 gram for the main color and the Cool Bundle for the stripes. I have laid out the stripe pattern, but you can make up your own.

I did the Large size. If you need it to be larger, just work more increases as set. There is enough yarn with what I had to make it larger. If you use the 50 grams of Woolstok you will need 2-3 skeins.
