A couple (or a few) years ago I participated in a block exchange of Churn Dash blocks that was organized by Barb. I had sewn sashing to 2 sides of all the blocks and finally decided to sew them together.
Here's a picture of them on my design wall before getting them all sewn together.
I might add a border and then use some of my many random HSTs to make another border. I think I'll sleep on it.
