I was unhappy with how the Sweet Scallops Shawl was turning out, so I abandoned it to try the Tranquil Wrap (free on ravelry here, or on the Lion Brand Yarn site here). I am using the same yarn I was using for the Sweet Scallops Shawl. So far I like this wrap better, and it is growing quickly!
I don't know what went wrong with the scalloped shawl. It looked so pretty in other people's pictures. Maybe I'll attempt it again someday with different yarn.
