Hello, lunchbox swappers! This week I made replicas of plastic grocery sacks -- another thing that I often see people carrying their lunches in.
Because I intended to use mine for groceries, I made these bags out of vintage percale sheets and pillowcases, which I thought would be durable. I thought the percale was also a good choice since it's an easy-care cotton/poly blend. (Regardless of how cute they are, I have no intention of ironing my grocery bags!)
The bags have a tie closure at the top, which can be used to tie them up like this:

They're each fully lined with a contrasting print. I made the ties from the lining prints, so you could see both prints on the outside of the bags.

Most of the bags like this that I've seen have a seam on the top of the handles. I didn't like that idea, since those seams are, in my opinion, kind of clunky looking. These handles are sewn into the top seam of the bag and reinforced with several rows of stitching -- two to the seam allowance on the inside, and two through all layers of the bag. The interior/bottom of the bag is the only "raw" seam. I finished it with several layers of zig-zag stitches and, since these are utilitarian bags, I don't think it will be particularly bothersome.
I had never tried out the pleating technique I used for the sides, but it was super, super easy. It accomplishes the same thing as "boxing" the corners, but the way the pleats are sewn makes the bag much more compact when it's not in use. I can see why, basically, all plastic grocery bags are made this way, it's a genius design!
If you're looking for ideas for all manner of shopping bags (far more patterns than the one shown on the cover) I recommend Japanese Craft Book ISBN 978-4-8347-2571-1, which I purchased at Kinokuniya in Beaverton. The strap concept for my bags was inspired by one of the bags in this book.
Unfortunately, my sewing machine became quite ill during their construction, so you'll probably be seeing some non-sewing posts for the next week. I'm hoping it will be in good repair in time for next week's lunchbox inspiration post!
