This is looking great. Yes, flannel will stretch much more than cotton but you will do fine. Of course you did not pick easy blocks either.....this is going to be beautiful. And really your points look good.
Whoa!!! Great blocks!!! Cute fabrics!!!
Very pretty. It will be lovely when you are done
Beautiful, Cindy! This is going to be such a warm, soft quilt...can't wait to see it all finished up!
