Hi all,
I've been watching this thread with a lot of interest as I am a Halloween freak. Unfortunately, postage makes it impossible for me to participate. I am in Canada and Canadian postal rates are rude and it seems to take an average of two weeks between Canada and USA, or USA and Canada. The only way to use the US flat rate envelopes would be if I made a couple of special trips across the border for mailing and pick-up. (Flat rate to Canada seems to be $20. To USA $6.) At two hours plus for border line-ups, that won't happen. Only teeny, tiny possibility is if we need to cross for another reason and I know ahead of time.
I will continue to watch the thread. There are some great blocks showing up. You all should be proud of yourselves. I hope you show off the finished quilts, too.
