They are sometimes called gators, sometimes neck warmers, sometimes other things that I can't remember now. If you join Ravelry and search their pattern library for neck warmers, you will find over 200 knit patterns for them - some free, some not, some girly/frilly - some not. Or you can do a google search and you'll find them.

Here are just a few:
