I'd like to say that my conscience is as green as my favorite burlap tote. In truth, I switched to cloth shopping bags when my curious baby started wrapping plastic sacks around her neck. (Everything is a scarf to her, including underwear.)
I just couldn't live with the danger of suffocation. Sometimes I forget, but shopping with cloth bags is largely second nature.
Now if only I could get another pair of arms to carry all these yard sale totes!
