The only place that I've seen such lovely cape patterns have been in magazines and Wrap Style, I've not seen any free ones, but would love to know if you run across one!

There is one almost exactly like it in Wrap Style. Check your local library. They may own it and if not they can borrow from another library for you on Inter-Library loan.
