Make a tote bag, of course! (Well, out of the empty bag, anyway.)
I found this vintage seed bag in an antique store and just love the graphics. I used a plaid twill fabric for the lining, shoulder strap, a top band and the bottom. The green graphics were all on the front of the sack and it was big enough to use for the front and the back of my tote bag. I still have the whole back of the sack to use for another project.
