Whit at The Purl Bee has a knitting pattern to make this spring hoodie.

I have a favorite zip-up sweatshirt that I wear all spring long. I love the way the hood spills over the back of my coat, and I also love to pull the hood up over my head when spring’s breezes turn unexpectedly chilly. I thought it would be cool to pare my hoodie down to its most essential part, the hood itself. I knit up this Spring Hoodie to be my all-occasion companion, with a cowl neck for elegance and warmth and a bright ring of color for fun.
