My son has a nylon glucose bag that is really light and comfortable, and which he really likes:
But it does not have a shock cord assembly outside – it would be useful to have one so as to be able to use a Frio bag on the outside when needed. I have been looking for the right parts and ideas to sew some such thing together on his bag, but I am not finding anything just right - neither the parts nor the right design/ tutorial. I am looking to do something more or less like this out of shock cord:
For things like this, being durable is always more of a concern than aesthetics. So for sewing things like this, I use braided saltwater fishing line. Make sure you use braided, not regular fishing line.
Something like 40 pound test is easy to work with, but would withstand just about anything you could dish out.
Use a big needle sewing it. After you have knotted it, singe the ends first, and then paint the knot with a coat of acrylic (something like a fingernail polish). That will never come apart.
That’s what I mean. I did try just folding over some strong nylon strip, but there was quite a bit of friction. I wish I could find just the right thing, something like this:
On the contrary! Great pic – that’s just what I am trying to craft on the LC nylon bag. But I have not been able to find nice tie-out loops to feed the shock cord through.
