Merry Christmas!

The other day I saw a quilt that was made with strips of a jelly roll sewn together almost like a jelly roll race quilt but then they had cut longways up the quilt and inserted a strip of flying geese which had long sides pieces of fabric allowing them to be offset from row to row.

The first set was centered, then the next was right aligned, the next was centered, then left aligned.

I am still very new to working with triangles in my quilts and I've made some "regular" flying geese but I don't know how to make flying geese where the side fabric is longer other than just sewing on a block of matching fabric to the side of a standard flying goose.

Does anyone know if there is a better way to do this?

Here is a quick and dirty picture I made of what I am trying to describe. In my picture, much like in my quilts, the points don't line up exactly, but pretend they do.
