I took a piece of 3x3 inch square mountboard & rounded the corners.
I drew a border & string figure with a pencil, then used a Sharpie pen to go over the pencil drawn string.
On the back, I drew a grid to divide it into 9 squares, numbered them from 1 to 9, then cut them up.
I took each piece to work on individually, rubbing out the pencil lines once each piece was finished.
The pieces were put back together.
In Zentangle speak, this is called an ensemble.
