I took my whole pile to the post office and told her what was going to happen. She said that as long as the ones coming back would weigh the same and the ones going out, that she sold me a postage paid envelope with just the right amount of stamps on it. There was even a postal hike between the time when I mailed it and when it was coming back and she calculated that in. I was surprised at how much it was....over $7.00. But I got it all and made the quilt. Happy endings all around.
