Just a warning to all who use the flat rate postage-paid light cardboard envelopes from the post office -- I received two in the mail today. It was raining all day long. They did not get wet, but the dampness turned them into mush. I was fortunate that the contents were all there because there were huge holes where the cardboard just split apart. These pouches only contained fabric - nothing hard or pokey. Imagine if they had gotten wet. From now on I am going to use lots of tape.
