Those scarves are beautiful...!
And the funky hat (purple/green/blue thing) was origionally designed for working on strait needles (I changed the pattern a great deal and used dpns). I've another hat I made a while ago that is also made for strait needles.
In fact, I can think of at least 4 patterns I've found on line and in books made on st needles... So, the hat world is your oyster!
