I'd like to make a quilt similar to the one in the thru-hiker tutorial http://thru-hiker.com/projects/down_quilt.php
I'm guessing there's cheaper sources for materials though, and if you guys could give me some leads that'd be a huge help.
For 800fp down i'm looking at $6.50/oz at http://theperfecttrees.com/products.html#down
As for fabric I'm not 100% sure what'd be best for me. I need something breathable, so cuben fiber is out. I hear tyvek sews poorly and the stitching rips out, I'd trade some weight for durability in this case. So what options are left, Silnylon and proprietary fabrics like the "momentum .9" that thru-hiker sells?
