For starters, you actually have to make them first, right? I made mine with a specialty ruler (Companion Angle, and EZ angle rulers). You can make yours using a specialty ruler (also shown via the quiltville link) or there are other methods of making flying geese well explained by Connecting Threads
I assembled my flying geese making sure the colors were well distributed.
It is assembly time!
Next I am going to add a 4" finished blue border around the outside!
