First I would have spray basted, then I would start at the edge about 1/2 way along the side and go across.
Next. 1/2 way across the end and go the full length.
After that I would continue on, wherever logical. As I get to the edge then I travel/stitch along the outside edge that will be covered with the binding to where I want to stitch next. If that's too far away, then I'd lockstitch leaving ends to bury. Then go to the next spot and start again. And so on!
