I only unflaked it and flaked for demonstration. I have used a Falteimer cube, but only briefly. They seem to be of high quality, but to me, are a bit pricy for what it is. Of course If I had to sell a tarp bag I would charge the same amount probably!
I am not proposing that this idea makes the cube obsolete, it was just something I was tinkering with and thought I would share!
I need a sewing machine...
