Lets see...
I buy about one bag of flour per year, havent bought a *bag* of sugar or corn meal in a couple decades.....
Would we have to wash the FORMALDEHYDE out of the bag after we emptied the flour out of it, before we sewed with it ?
Did you know the cloth groceries bags were tested by permission of grocery shoppers in several grocery stores a few months ago, and over 90% of them had some level of salmonella and/or E. coli contamination? Do you realize how many people do NOT wash their cloth grocery bags after every use ? It was interesting.. just a thought.....
