I ran across a blog entry from my friend Angie, the super DIYer, about paper vs. plastic. I've heard rumors that some cities are requiring retailers to stop using plastic bags and noticed that Target started printing other uses for their bags. We use both paper & plastic & have a few cute canvas totes from Olivia's Market that I use as much as I can. (The bag is great for bringing all of London's clothes back and forth from preschool. We go through a lot during potty training.) We also use our paper bags to keep recyclables. That way we don't have two huge garbage cans in our little kitchen at one time.
My mom started using canvas bags for groceries years ago. In college, I would usually ride my bike to the grocery, so the backpack was my bag. After college, I bought some canvas bags that I used for quite a while. For some reason, over the past few years, I found myself using plastic more and more. Sorry mother earth. It's time to get back in the habit.
