The Ballet Collection is available as individual patterns or as an e-book on Ravelry.

Ballerina is a featherweight, slightly oversized poncho in delicately transparent merino and mohair brioche. It has a round low-cut neckline to accentuate your neck and collar bones, and its folds will gently brush your arms as you walk, making you feel as glamourous as a ballet dancer.
