Quilt Design – straight baffles with some curves

I am tossing around some sample baffle designs. Made a 30 degree long/wide quilt for a friend.

1.1 oz ristop nylon both sides.

Zippered footbox. top cinch, buttons, pad straps….  EE copies, really.

750fp down

2″ baffle and loft. 20% overstuff approx.

85L x 58W top and 46W at the bottom.

You think this slight taper will keep the down from shifting too much?

Thanks!

PS:  To make it a little more “professional”  I got some sew on labels from wunderlabel.com.  Highly recommend!
