Update your canvas tote bag collection (I know you're not using plastic bags at the grocery store anymore) with one you made yourself. Here are the top 7 tote bag tutorials on the web.
Two-Hour Tote Bag, perfect for some standard canvas fabric and, for the straps, nylon webbing.
Martha Stewart's tote bag, the largest bag in the group. She actually calls it a beach bag, but it would work for any kind of serious hauling.
Morsbag, no frills, just the standard canvas bag. There is even an animated version of the instructions, so it's a cinch to follow.
And, finally, a knitted tote bag for smaller loads. Yes, it has holes, but it's too pretty to pass up so just don't buy any grapes.
