I set out to find an easy tutorial since I am still a novice. I found this one:
This tutorial only required me to learn one new stitch, the treble crochet stitch, so I googled it and read a tutorial and did some practice stitches. Now I know a total of 3 stitches. Woot woot!
Anyway, for the most part I stuck to the tutorial, except I did not make my scarf as wide. Mine is only about 9" wide. I had to undo and redo it a few times, but I am very happy with the end result. The yarn I used is super soft and thick.
