Here is how to make this: (Hmmmm, is this garbage?)
To create the square bottom of the bag, fold the corners on the diagonal (matching the bottom seam with the side seam) and sew across about an inch to two inches in, it depends on the size of your bag and how big you want the bottom to be.
Now, use some scrap fabric and make some handles. I have made them about a foot long by about 1" wide up to a foot and a half long by about 1 1/2" wide- either size works well. The pieces I cut are about 3" wide to start with and then I fold them over in thirds and zig-zag to close(don't worry about the ends, just the sides are fine). I used an old dish towel here.
After you have stitched all the handles, turn the bag right-side out and... VOLIA! You have your own re-cycled, re-usable, and re-cyclable bag for your shopping eco-enjoyment!
and here's a shot of the inside too...for reference : )
These bags are stout! If yours has a paper covering on the bottom opening, don't remove it, just cover it with a piece of fabric to re-inforce it.
Hope you all enjoy making these and the conversations they start when you actually remember to bring them in to use at stores. : )
