I did it--my first crocheted project!
I used the Easy Ribbed Scarf pattern from Tracie Barrett. It's free here!
It was a good pattern for a beginner. I didn't know how to do one of the stitches, so I found some instructions and videos online. The stitches aren't perfect, but they got more even as I went.
I'm looking forward to my next project--a scarf for Chickie with yarn that she picked out! It'll be so fun to wear these scarves...in about five months. Sigh.
