This block was a fun one. It sortof blew my mind, actually. I never would have known you could do this, unless I was shown-and it is so SIMPLE in theory, too.
It's called a Disappearing Nine Patch. All you do is stitch nine squares together-to form a nine patch.
Then you cut it in half. and in half again (to make quarters).
And rearrange....and rearrange...and rearrange.
After this many variations I gave up. I am sure there are more. It's crazy you can get SO many fun, interesting and complex looks by such a simple dimple technique.
This is the one that I chose, and stuck with. It is on its way to Germany as we speak.
