By way of an update, I've received blocks from all but 7 participants, and 6 of the 7 have confirmed mailing dates, so we're in excellent shape.
I will have time during the week to do the swapping as soon as I get the rest of the blocks, and assuming I get the blocks early next week, I'll begin mailing out packages by late next week.
Thanks to everyone for keeping to the schedule, for staying in touch, and especially for producing these marvelous blocks. This is a truly beautiful collection of your work. I know you're going to love your quilts!
