I approached the border feathered units the same way I did the inside feathers. The only difference was I cut myself a template to mark the curves of the spine of the feather. I used the same curve for both the shorter side and the longer side. The long side is about 3/4" longer than the short side. I just adjusted each segment a tiny bit - you can't even see the difference but it takes up that extra length to make the design flow.

This last photo is the finished border feathers...now to get them all marked onto the quilt
