I have just read all 415 of the posts for this swap. I wanted to make sure I was doing it correctly. Gleanings from the reading: Measure each section and square to 4 1/2; put label on the back of the block in case there is any residue. Make one extra block, NOT one extra block for each set. Be sure to include the mailer to get your blocks back to you, with proper postage which is stamps not metered mail.
Thanks so much Armylady.
