Another Q: is IX downproof?? if so, than wouldnt it make an absolutely outstanding down quilt material, since it would not only have the warmth of the down, but the IX would also have its beloved dead air space. it would seem that it would make a really cool looking quilt that would be just as light as if ripstop had been used, but it would have superior thermal values/properties! AHHH! I now want to make a down quilt out of IX instead of just an IX quilt! this DIY business is so stressing haha!!
Why gross grain? I've done both and I just really don't like the ripstop channels, at least with the lightweight ripstop I use for the shell. It will work and that's the beauty of DIY - you can adapt any design to fit your needs. I'm not sure if they're still doing it that way, but that's how KAQ quilts at least used to be done. Personally, I really like the gg binding.
Yes, it is downproof. I know HammockGear.com has done some experimenting with down and IX. IX is not tough like fabric is though (it's very easy to slice or poke a hole in), so if you don't use a shell material, you'll need to be VERY careful with your gear - VERY careful. Getting a hole or slice in IX alone isn't a huge deal, it's an easy fix - but if it means you're spilling expensive down, it becomes a big deal.
Experiment. Change. Adapt. DIY is fun.
