The white edges are the backing material and will be covered when sew to the item. It might be a broach instead. Metallic gold floss is the devil. This whole project was Satan's Satin Stitch.
Lucky Seven was the Jaeger that Herc Hansen piloted in Manilla with his brother Scott Hansen. It all went totally south when Herc saw in the drift that his brother had done something so horribly wrong that it pushed them out of the drift. They barely made it out alive. Herc reported Scott to the PDCC and Scott was dishonorable discharged. This is canon per the screenwriter and you know how I love my Hansens.
