Making my own Semi-Rectangular Sleeping Bag. Where to buy wider fabric?

Check out DIY Gear Supply online. They have 72" wide 1.1oz ripstop nylon 2nds, lime green only. I just made my first quilt today with that exact fabric. It's functionally perfect, cosmetically too, really.

Is 72" wide and $3.20 per yard so ridiculously cheap. You can check out my MYOG quilt thread to see what the green quilt looks like. (Lime green as in the outside of a lime)

After seams, you'll probably be left with 71"-70" usable width. If that is long enough for you, that can be your head to toe length and you can get 4 yards (8 yards total for outer and inner) and do the method you mentioned above.

Just throwing in my 2 cents as well…I used the lime green in a 72×58" "double quilt" that I finished up not too long ago.

I'm pretty happy with it and I'll be uploading pictures in the near future (just finishing up a few things with it like pad attachments).

Did either of you guys use down? I am wondering if it is downproof.

I bought some 1.1 2nds nylon from DIY supply. It was a while ago though – dark green.

I made a test sample with down and it appears down-proof, but that's not the same as a garment or sleeping bag you roll around in. 850 FP down.

Andrew, I used both ebay pillow down as well as 850FP from Wilderness Logics when I ended up being short 1 oz of down.

The pillow down was says "800FP <25% feathers" on the tag and was $50 for 18oz ($3.50/oz). I was pretty happy with it and for the price it's a great value, however it's a real pain to move into the quilt though and stuffing individual baffles really makes you re-think if it's worth the trouble–kairo style baffles would ease the suffering dramatically though.

Both sources of down have been working well with the 72" ripstop…the inner on mine is Nobul1 and it has been leaking small amounts of the pillow down but nothing I'm concerned about.

Another thing, I'm currently making a tapered quilt (essentially a Katabolic knockoff) for someone using 1.1oz ripstop from DIY Gear. I'll be stuffing it this weekend or Monday but I'm confident it will hold the down just fine.

"Calendared" (and DWR) should be the indicator for downproof stuff on DIY Gear.

What are kairo bagfles?

…basically kairo baffles are squares with the corners open so that down can be shifted all over the quilt…traditional baffles are like tubes that are closed off, so down can only shift within the tube.

Advantage of kairo is that you can stuff all the down through one opening and then sew it up and shake it around to finish…with the traditional baffles you have to stuff each baffle individually and then sew it all shut.

Here's a thread that compares the two:

I'm planning my first attempt at a kairo quilt in the next month or so. From my understanding, sewing the baffles to the 1st shell is a breeze (faster, easier than traditional) but the 2nd shell is a pain because the baffles run in both directions.

Here's the layout i used for my karo quilt.

I'm 5'10" 160lbs. Filled with about 10 oz of 850 down. i think it's good to about 25f.
