I guess my next question would be, where to find fabrics with patterns simliar to the Ansata design?
Trying to find a suitable pattern would be difficult, but there are so many designs of fabric out there so definitely possible. Try any local fabric stores, then look online on sites like Ebay.
This blogger actually
sewed on the designs... that's a whole new level of dedication to becoming Jocasta. Not massively difficult, but time consuming to the maximum. Pictures of it are towards the bottom, just scroll till you see it.
