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?

Silnylon is not breathable.
Regular 1.1 oz nylon ripstop is definitely the way to go for a cheap, breathable quilt.
Outdoor Wilderness Fabrics is a good supplier for this, as well as for anything else you would need... except for down (as far as I know).

I was thinking ripstop, typing silnilon :S

What's the actual difference between firsts and seconds when it comes to these products? Theres quite a gap in the prices.

Most of the 1.1oz ripstop seconds I've seen are cosmetic seconds only.

i.e. a couple colored lines running down one section of fabric, or a discolored area.

Just make sure it's downproof.

Hi Ankar,

I would suggest going with the quality material from the place you got the info -thru-hiker.com

That way you are assured of downproof quality material that will last a long time and preform well in the field- a nice reward (and peace of mind) for the many hours you'll spend creating your personalized gear.

owfinc.com also sells .9oz ripstop, similar to momentum 90. But the best price for a down quilt is usually the thru-hiker kit.

+1 to tim, i shopped around a bit and thru hiker was the cheapest for the amount of fabric you get. If order from two places youd have to pay shipping twice and it would most likely end up being more expensive. I was so impressed at the comfort of m90 it was worth the 30 dollar upgrade IMHO.
