The applique bits were done quite a while ago for this one, all that remained was sewing the squares together and sashing them out a bit. The edges didn't quite end up even when I sewed the four patch together, so I ripped it out and tried again. It didn't end up any better. Then as I was ironing them, the iron left dark marks on the edges. So I washed it in the sink and tried again. Then as I ironed it again, the same thing happened! I guess I would have been better off letting it be the first time.
Ryan is my happy block holder today, he was nice enough to take a break from his video game to pose. Block C11 is crossed off the list. Next?
