I've always sent my fabric postcards as is through the mail. This is only my second month here on this swap, but I've been sending fabric postcards to my daughter for 1-1/2 to 2 years now, & they always arrive intact. I feel the hand-cancelled stamp adds an authenticity to the postcard, but I can't wait to try embellishing! And the post office I go to is used to my postcards -- I've got them well-trained!
