craftgrrl | Pictures behind the cut.

So here's the deal. A friend gave me these awesome coffee bags, and I really want to sew them together and make a tote, for I need a new one. The problem is that they're really oddly proportioned, so that my bag ends up being either really fat and short or really narrow and tall. i have four of them, and they're about...8"x12". i also got material that, while it doesn't match whatsoever, i love it. and it's really thick and supportive, so would be good since i want to use this for school.
what the bag and the images on them look like

detail of the bag- you can sort of see the material type and whatnot.

and the liner material i got.

so, how do i do this? i'd obviously have to use some material on the outside...otherwise i'd have to cut apart the coffee bags, and i don't want to do that because i love the images. ideas? thanks!
