Don't leave those ikea bags out in the sun, they fall apart rather...quickly....

I came here to say this... Those FRAKTA bags ( http://www.ikea.com/us/en/catalog/products/17228340/ ) are 100% polypropylene (thin strands, even). Polypropylene breaks down under ultraviolet light. The fact that the weave of the cloth is made from fine strands of polypropylene means that it will break down very quickly in the sun. There's a "fix" though that should be good enough for a camping trip or two! Coat the b…

Making a cheap bag into a greasy, sticky cheap bag doesn't seem like a net gain.

Cordura, which is what most robust backpacks are made of, is surprisingly expensive.

Tyvek would probably make more sense for a project like this. $30 will get you 10 yards on Amazon

Tyvek also breaks down in UV light.

Whats up everyone. I am the maker of the website and the backpack. This was my first sewing project, but it turned out much better than I expected. I loaded the pack with 30 lbs to test it out before I take it on a multi day trip, and it had no problems. I'm currently working on moving my images to a remote site so wish me luck on keeping the site up.

Love the spirit of the project! I look forward to seeing if you iterate/modify/improve on the design after using it.

Oh, it was obviously cheaper. But he spent 25 hours stitching. If I were doing that, I'd spend $25 getting the properties I wanted.

If your hourly rate is $10 dollars an hour, then that works out as a fairly expensive bag!

If you do it in your free time, it's an extremely cheap bag. People tend to overestimate the value of the time they spend not earning.

If you're spending that free time with family or friends or doing something else you value significantly, then sure, there's value to that time. If you're browsing photos on Reddit or watching TV, it's probably not that valuable if you honestly evaluate it.

that's pretty cool. reminds me of me wanting to learn sewing, stitching and that stuff. knowing how to do that allows to alter suboptimally fitting clothes or repairing them. not to mention ... what this text is about ... designing yo I'mur own clothes, bags etc!

I am positively surprised to learn that a product called 'Butt Paste' exists. Still seems that economically speaking it might be cheaper to create such a backpack from a more suitable cloth instead.

How about Anti-Monkey-Butt-Powder? [1] Popular in motorcycling communities.

Is that Pacific Beach drive? I use to live right down the street from where that pic with frankenstein was taken, over on Riviera Drive.

I don't think tyvek would be strong enough for a backpack. It is used a lot in backpacking for ground sheets and even shelters.
