I apologize for the sporadic appearance of block instructions.
I'm still struggling with the "monster" block and it's really holding me back. I keep hoping I'll see the light and find a simple solution, but not yet.
Here's an easy one.
Trace or print the block diagram onto foundation paper, number, and cut out as in the photo.
You have to mirror the diagram.
Out of background fabric, cut two strips 7/8" x 2 3/4".
