I've made a few curved flying geese before using directions in the book Flying Colors by Gail Garber. Slightly different techniques, and I love the book, but there's nothing like a live teacher, in person, who can give you great tips for saving time, accuracy in piecing, and so much more.
I also took a workshop from Irelle Beattie, using her Not So Twin Strips pattern. She's taking a break from her Etsy shop at the moment, but at some point, you may be able to buy the pattern there at JibberishDesigns. Here's the layout as I was playing with it a couple of weeks ago.
Changes have been made, but I'm almost done sewing the top together. Another super fun technique!
