Approaching the Down Coat part 1

I’ve decided to ruin my winter vacation by making a down coat. This and the bathing suit are the most difficult garments I’ve tried to make. I bought the Altra Western Down Parka Kit on eBay. My plan right now is to design my own coat and use the kit’s feathers and some of the instructions. The drawing of the man sewing his own parka was on the side of the box. It's serving as inspiration. He looks so happy. He’s saving 30-50% of the retail cost by sewing the parka himself, say the instructions. The blurry picture of the candle is me searing the fabric. This stuff frays like crazy and searing it melts the edge a little to prevent this. It takes forever, so I’ll probably use my serger instead. I’ve included pages from my sketch book so you can see my thought process.
