I agree with NZquilter. Please, make the blocks you want to make. I doubt we'll all pick the same ones or the same fabric.
I would love to find some sort of other pattern involving a Sunflower. Red's is gorgeous. But, that is only 4 blocks to swap out. So, I will continue to look until I find a pattern I like.
I also have 2 other pieced blocks that I'm planning to make. And, they will be 12 1/2" sq. I wish I could find some Fall leaves fabric locally. But, it is the wrong time of year for that. So, will concentrate on using what I have. It is fun to see what I can make work.
I got so addicted to the summertime swap blocks that it is hard for me to move into Fall. I am still working on an old (2011, I think) summertime block swap top that I am re-working to make it bigger. I just wasn't quilt ready to let go of summer. lol
