A four patch and a split square are both very simple units.
Using 2 of each I designed this simple block.
The question is: what can I do with it?
Often I use color to change the way a block looks. But not today. Today I'll maintain the original block design even when I change color. I want to explore possible patterns using one simple design element.
Some of these designs have strong graphic elements. For some the design isn't as strong as it would be if the pattern were repeated. While others simply rely on color for their appeal.
