grocery bags

My mom has said she'd like some reusable grocery bags, so I have an excuse to make a few more! And to use that rubbery "techno taffeta" that I've had no idea what to do with. I was surprised at how well the "techno taffeta" went with that iridescent fabric from Joann; these bags fold up much better than any of the others I've made. I've made two in this fabric combination, and I'll probably make a few more, since I still have more of both fabrics and I like the results a lot. I took some pictures of the process, too, since how the folding-in of the outside edges works always seems somewhat hazy in the tutorials I'd read; it took me awhile to figure out how simple it actually was.
Green Reusable Bags: Two more reusable grocery bags. The outside is some kinda of synthetic iridescent fabric from a half-off red-tag sale at Joann last year, and the inside is that rubbery Vera Wang "techno taffeta." I was surprised at how well the bags made with this combination folded up! The folded up bag is definitely flatter and more compact than the other fabric combinations I've tried.
Grocery Bag Side Fold Outside View: From the outside, the bags look like there must be some sort of accordion thing going, folded in from the middle of the side, right? Wrong!
Reusable Bag Unfinished Inside View: Turned inside out, the outer edges are just folded in towards the middle, lined up with where the pocket comes to on the outside. From there, I just serge across the bottom with a 5-thread safety stitch.
