Wow! Amazing shawl, all you have to do is make a basic shell stitch shawl, add crochet roses with dangling rose leaves to each end, simple and lovely! I'd rather have it as a scarf though instead of a shawl. Might have to think about tackling making this.
I like the idea of edging only one side of the scarf... I might have to try this with one I've already done!
