## <mark style="color:blue;">One Patch Blocks</mark>

**One Patch Blocks** are quilt blocks that fill the entire [*cell block*](https://glossary.prequilt.com/cs#cell-block) of the [*quilt grid*](https://glossary.prequilt.com/qs#quilt-grid-also-digital-design-wall) and require no  piecing. They can easily be added to the digital design wall by using the One Patch Block tab nested in the Blocks Tab on the [*Quilt Editor*](https://glossary.prequilt.com/qs#quilt-editor)'s [*left side control panel*](https://glossary.prequilt.com/cs#greater-than-left-side-control-panel).&#x20;
