I just wanted to post the steps that I take to make shoulder straps for my backpacks.
The materials I used are:
-4mm foam mesh from Rockywood or you could use 3D mesh from thru-hiker
– 3/4" Grosgrain
The first thing I do is mark out the pieces I need to cut on the back of the fabric. I cut a template out of mat board to make this task easier. You will need to cut 4 straps out of the foam mesh, 2 facing to the left and 2 facing to the right. I also cut out a left and right strap from the cordura. I use the cordura to give the straps some extra strength, you could by all means leave the cordura out.
Next I Take all the pieces that I cut out and separate them to their proper sides. You will want the backs of the foam pieces together with the piece of cordura in between them as shown here…
Once the pieces are together I sew them together
I then add a strip of either grosgrain to webbing about 9" up from the bottom curve of the strap. This works good if you use a water bladder to keep your tube in place.
Next I attach the grosgrain trim. I first measure out how much I will need and cut the proper amount. I then fold the grosgrain in half and put a crease down the middle the length of the strip. This makes it much easier to make sure you have the edge of the strap in the middle of the grosgrain. I then start on one end and sew the grosgrain on the whole way around the strap. The curve of the strap can be tricky so take your time.
I then change out thread, I use a nice complimentary color of heavy tread and add my ladderloc and webbing. here is the underside of the strap
I then continue to bar tack the whole way up the strap to the top. I leave about 6" between the ladderloc and the first bar tack to attach a chest strap. I then continue to add bar tacks every 2.5" to the top of the strap.
And that is pretty much it. When you attach the strap to the pack I make sure to run a couple of bar tacks over the webbing so it is sure to hold. The webbing is the strongest part of the strap, the other material just disperse the weight of your pack. Here is a few closeups of the strap attached to the pack.
So this is how I make my straps. I hope this will be useful to anyone thinking about making a pack. They are really fun to make, they just take some time planning. If you have any questions about any of the steps please feel free to ask!

Awesome guide Chris! Thanks a ton for sharing that, I will definitely be using it on my first pack. Quick question, where did you get the exact shape for the straps? Was that just a common sense move or did you base it on something? how do they feel? I have seen a lot of different strap shapes, some with more or less drastic curves, and am trying to figure out the benefits of the varying styles.

I have a new pack idea in the works. The first thing I thought when I saw your was "How's he making those straps?"

Nice! Thanks for sharing! Any idea on how many miles before these straps flatten out?Jan 20, 2011 at 8:56 pm #1686500Ken ThompsonBPL Member

Hey thanks! Perfect timing. Have a pile of pack bodies without straps in the other room.Jan 20, 2011 at 9:27 pm #1686514Larry DyerMember
Very nice. I'm bookmarking this thread for when I work up the gumption to get serious with the sewing machine.Jan 20, 2011 at 10:05 pm #1686527stephan qBPL Member
I've had a MYOG pack plan in the works for some time now, and was planning to just use straps from an old or damaged pack. Now i can make my own. Thank you for the step by step info.Jan 21, 2011 at 5:33 am #1686564Matt FBPL Member
Thanks Christopher – This is extremely helpful!

Hey glad to here this is helpful to others out there and I hope it encourages you to give it a try. Here is a jpg of the general shape and dimensions of the straps I make. I like the strap to be around 2.5" wide 21" long. I have found that the bigger or harder the curve to the ladderloc, the better the straps lay with a chest strap attached. But hey give it a try and see what works for you that is all part of the fun!

Chris, I saw your tutorial on the spade as well, very very helpful!
Do you guys remember that show aired on Fox, about 10 years ago, called "Magic's Greatest Secret's Revealed"?
This is like the same thing, but for MYOG. Freaking awesome.Jan 21, 2011 at 9:14 pm #1686894scott NelsonBPL Member

Great work on the packs and thanks for letting us see how you make your straps. Sewing the gross grain around the perimeter is tough to make come out right. So hats off to your work! I am wondering if you really need the 3D foam on the "outside" of the shoulder strap "away" from your body. The cordura will stop sweat from wicking thru to the outside. Maybe just two layers, mesh and Cordura? But then maybe you would feel the 3/4 webbing too much without the second foam layer? I have also made and like the shoulder straps that Jay Hamm explains on the "5 yard" BPL Project. ScottJan 22, 2011 at 7:43 am #1686993Daryl and DarylBPL Member

Do you know how much they weigh?
Would that 4mm mesh be stiff enough to lie flat under the tension of a waist belt?
Keep up the good work!Jan 22, 2011 at 10:09 am #1687043
You could by all means leave the top layer of foam mesh off and just use the cordura or xpac or what ever fabric you wanted. It would take away from some of the padding, but you could always put in a layer of foam. I have tried some with a layer of foam, and they turned out nice but add more weight, so you have to think about what you want, less weight or padding.
The weight of these are around 2.6oz for the pair, 1.3oz for each strap.
I'm not 100% sure what you mean by laying flat under weight…
I have tested them out with 25-30lbs, which is way more then I want to carry normally, in my pack and they stayed flat.
