## Merging Block Cells
In this tutorial, we'll show you how you can merge multiple block cells on the quilt grid to create a different sized quilt block.
It's always best to start with a quilt grid made up of smaller blocks that are combined (merged) together to create bigger blocks. You cannot breakdown or divide a larger block into smaller components, but you can always combine smaller blocks to create a bigger block.

### How to Merge Cells to Create Larger Quilt Blocks
1. On the quilt grid (or digital design wall), click on **all the** **quilt cell blocks** that you want to merge (or combine) together to create a larger quilt block.
1. **NOTE**: To select a cell block, click on it. Once selected, the cell block will be outlined in blue.
2. With the 4 cell blocks selected, click on the **Merge** button () on the central, vertical toolbar.
3. Once merged, the 4 individual cell blocks will be merged into 1 larger cell block.
4. Continue merging smaller common blocks into larger blocks until you have your desired quilt layout.

### How to Unmerge Cell Blocks
If you want to undo a merged block, that's not a problem!
1. Click on the **quilt** **cell block** you want to unmerge back into the smaller common blocks.
2. Click on the **Merge/Unmerge** button () on the central, vertical toolbar.
3. Now the larger block has been divided back into 4 individual cell blocks.
