Design*Sponge. I didn't mean to do another re-post today, but I couldn't help it. This lunch bag is just too cool. The tutorial is by Matt of Wood & Faulk. Looking through his site I was very impressed by the style of his work. It is definitely masculine and I think Nathan would love it, but I'm pretty crazy about it too. I'm in love with his wool camera wrap and the old-school book strap (another tutorial for Design*Sponge).
