Since I wrote a tutorial I figure I ought to have a plan for this thing!
I laid out stars and hexagons into large hexagonal "blocks" consisting of 12 hexagons and 7 stars each. I took measurements, then sketched. To help visualize the plan, I arranged a few hexagon pieces until I had a pleasing shape.
Oh my. I believe I've begun a several-year hand sewing project!
Piles of what I have cut so far. Now to iron more scraps, trace more pieces and cut! It's an adventure, right? :-)
