For the most part, this block is pretty simple. It's just an Ohio star with some stuff in the centre.
I started off the the flying geese. Then I laid everything out to see if I thought I'd like it. When cutting things for the centre block, I cut things a little larger and then trimmed for each round. This gives you a little more wiggle room. Something you really need when working with such teeny tiny pieces.
The first two pieces are a square-in-a-square. Then that becomes the center for another square-in-a-square.
