There was a time when I never missed an episode of 
Sewing with Nancy, but as the show evolved, there were more and more episodes on quilting, and since I'm not a quilter, I wasn't interested.  Recently, however, I learned through 
Nancy's blog that you can watch episodes online, so I have been doing exactly that.  The two entitled 
Sensational Scarves made me want to start wearing scarves again, so I ordered the booklet and DVD.  Last week, I found a knit fabric at JoAnn Fabrics from which to make the Infinity Scarf.  I chose this version because I don't like things tight around my neck (like turtleneck shirts). 
This fabric was the only one I found that was suitable for a scarf and which I liked.  
I will probably try making several more of these from silky fabrics.  Each scarf requires just a 24" x 30" rectangle, so I'm sure I can find something in my stash.
If you'd like to view the two episodes of 
Sensational Scarves, you can find them 
here and 
here.  They are a year old, so I'm not sure how much longer they will be available online.  You can also purchase the booklet and DVD from Nancy's Notions by
