That would be time consuming! Is it turned edge applique? It's very intricate.
I've booked myself in for a little free motion machine embroidery workshop, this weekend. I could teach myself but it's a technique that I really need to unclench for (I'm more of a precision sewer!) and I need to talk to some adults about things I enjoy rather than about the boys or about fucking jam and sodding Soreen bars! Unfortunately it's on Sunday so I can't just slope off on the bus by myself for the afternoon.
