We need help with this scarf

A friend of ours has this fabulous, soft, lacy, vintage scarf that we love. Because we received a donation of gorgeous silk angora yarn from the kind folks at Knit Purl in Portland, we've been looking for some good projects like this. The scarf seems like a great match for our new yarn...except, we can't figure out how to make this design.

If you can explain it to us, or even better yet, if you know where we can find a tutorial or knitting pattern, please let us know! Our knitters are eager to get started. If you can help us, please send an email to beadwomen@gmail. com. Thanks!
