My DH offered to take my pile of adults to the PO. He won't do that again! They really saw him coming and for most of the envelopes they charged him package rates. Japan was actually cheaper than some of the US ones. They made him complete a form for Canada but not Japan! By the end just 10 envelopes cost him $20. Think I will go with the 6x9 envelopes next time and see how they fare. AND go to the next town over and see if their PO workers are quilters!
