Here's my first down project. It's an underquilt. 48" center width darted to 36" at the ends. 2" differential on the inside 6 baffles(of 8). Made of 1.9oz Ripstop, black inside, OD Brown outside(though the pictures stink).
Baffles are 2.75". Max loft is around 3.5". 12oz of down from Stormcrow. At 26oz, it's a little heavier than my calculations said it should be for some reason. Not sure why. Hoping it will get me to around 20 degrees(maybe a little less in a pinch).
Took me about twelve hours working an hour or so per night over two weeks. Now that I'm done, I wonder why I was so nervous about doing it. Will start a TQ soon(using 20 denier this time to save more weight).
Sorry the pictures are so bad.
