I was finally able to use some of my lovely fabric from India, which feels similar to voile, and a piece of gorgeous shot cotton to make this infinity scarf. It is one large circle, and you can wear it looped twice or in other various other configurations.
I learned the hard way why I think it is called the infinity scarf. If you are overly confident and think you can figure out the construction of such a simple shape on your own, you'll likely end up, as I did, with a long tube you try to turn right side out, only to have it turn in on itself continually. Or infinitely in fact. Just read the tutorial on Anna Maria Horner's blog first and save yourself the frustration. She calls it the figure eight scarf, and she has some kits for it using her yummy new velveteen.
