Making a stash-able bag wasn't a requirement or even a desired feature. I also opted out from webbing straps because I personally hate them, even though they'd shave off quite a bit of the retail price. It rolls into the size of a Nalgene bottle if anyone found that interesting.

Here is the pattern I use for the fannys, see it's a double E ;) The width of the middle of the E is the same as the top and bottom with the zipper installed. Other than that, I'm so bad at math so someone else would have to explain how it all works.


Pattern layout options:
This gives you a square that could be used as a slit pocket. It's basically no waste.

This allows for more pieces per yard, but you end up with some waste.


For the liners, I just cut a square and trim it after it's been sewn to the zipper, because the ripstop liner is extremely flimsy and hard to cut more advanced patterns.

Unfortunatly this method is a waste of fabric. I had to make pattern layouts using professional software for a few days when our specialist was getting married and they taught me how to do it properly. For this kind of layout shown above I could have big problems. You should stick to  the classic front+back+bottom+two zipper pieces of Cordura.

The very small amount of wasted material (which could be salvaged) is more than offset by the drastic reduction in assembly time. Assembly time for me is only 1/3rd the time it takes to make a traditional box pouch with front, back, spine and zipper sides.

Agreed with GD, the time saved and the ease of assembly wins for me here. It's pretty much impossible to fuck it up in production since it's only straight stitches. I realize that in an industrial setting with 1000s of pouches and multiple people on the production line that this wouldn't work, but for a 1 man show this is a great way. And the side by side lay-out, if the open spaces are saved for slit pockets (I save them anyway), then you have 0% waste.

This is great I have a similar method but not as good for pouches or similar bags as the seam at the sides runs through the centre and doesn't allow the zipper to curve round

Though after a few test with this design I found it a little easier to see......perhaps I just need a bit of practice !
If anyone finds it a bit confusing ......start with a tote bag pattern and work your way up

I'll just put this here since it's pretty much the same;
I changed the neck, and did a donut style closure. I think donut closures are pretty cool, and it looks good regardless of how much you have in it. Black and RG looks pretty cool too.


Side pockets fit a 1L Nalgene each. It's 1" elastic webbing inside of the Cordura.


Now I have to make one of these for myself...

Black and Ranger is a good colour combo.
