Help creating a pattern for a mock neck hood..

Hi, I am very new to sewing and experienced in Graphic Design. I am using a fashion graphic design software called Clo. They don’t really offer much help on how to actually create patterns. I am trying to create a mock neck hoodie. I have the body and sleeves pretty much done.. I just am stumped on the hood. I am looking for something like the images below. I am getting familiar with the softwares special effects, but without the pattern.. none of that matters. If any of you can help me find a resource for how to make a mock neck hoodie, please comment! thank you.
