Michelle, I just PMed you about mailing my swaps. I thought I'd post too and see if anyone else has run into the same thing I did at the post office.
The PO lady didn't seem happy I taped my envelope. She actually said the PO where it's delivered may charge more postage when it arrives. If this happens let me know. She said "flat rate envelopes" were for "flat" things. I've been told by others who were told by their PO you could tape each side, just don't go over board. Maybe I used to much tape?
