What If You Made
A Churn Dash
Block...
...Then Cut It Into
Four Quarters?
You would have 4 small units to play with. I prefer to call them Quarter of Nine blocks since the original Churn Dash block was made by sewing 9 squares together and each of the new blocks is a quarter of those 9 squares.
There are any number of ways you could sew the Quarter of Nine blocks back together to make larger blocks.
