The Ammonite Scarf, first seen in Inside Crochet Magazine, is now available in US terms! ACK! I'm not allowed to sell it yet. We have to wait until April? The PDF includes several photos to help you see how these interesting dog-bone shaped motifs are joined "As you go". One skill you will need for this project is "Sc Foundation". Here's a good tutorial with photos on how to do that on The Crochet Spot Blog.
Of course, I also describe how to do a single crochet foundation in the pattern.
When I'm allowed to sell it, it will be $6.00 Practice your single crochet foundation until then.
