@briski asked how I designed this. I said it was worth a post of its own, so here goes.
Every week we have “laser thursday”, where we hang around late and make stuff. One thursday I told Tony, our chief product guy and cofounder, that I thought it would be cool to make a bag. He said that we would definitely need to hire some sort of expert because that sounded virtually impossible. I bet him that we could design a bag right there, having no idea if it would work or not.
We measured all my crap and got some paper and a pair of scissors. We mocked the bag up half-size with paper and scotch tape with all the features, like the hidden document pocket halfway down, sewn-in Trackr, etc.
When we liked it, I scanned the pieces, vectorized them in Illustrator, and doubled the dimensions. Then we printed one out of thick paper and taped it together. We tweaked it a bit. Then we printed it in cheap leather and sewed it part way up (by hand). That was a waste because it was perfect. Then we bought brass buckles, dyed some really fancy leather, and cut it again. This time we hired someone to sew it up because it’s like a 2-movie project.
So what software did I use? Paper and scissors, with a small assist by Illustrator.
Note: I’ve never made anything in my life out of leather before getting my first laser.
