I used these videos to learn from youtube: arm knitting by Michael's one more for arm knitting by Simply Maggie and finger knitting by Simply Maggie.
I used Lion Brand Yarn wool ease thick and quick in the color 'fisherman' you can find it here but I purchased it from Michael's. and I used two balls at the same time so every thing was extra thick, this was suggested as an option in one of the videos. and for the finger knitted ear warmer I only did two sewn together instead of three and used all one color.
over all this was a really fun craft that only took a few hours to learn and make and I'm already getting a lot of use out of the scarf!
here are some pictures of the final products:
