Crafty Gemini has a tote pattern that includes a how to video for $3.00 on her website. It's called the Must Have Tote Bag. I have the pattern and I have made about 12 of them. The tote bag is perfect for groceries, but the body of the bag is smaller than 24" (the pieces that make the body of the bag are cut at 20" x 20"). Her pattern uses a yard of material so if you adjust the size to make it larger you would have to buy more than one yard.
