# 03 | Add blocks to quilt grid
## Exercise 03
**03** | *Add 1+ blocks to the quilt grid.*
***Objective*** | To add our custom block to the quilt grid (that we created in Exercise 01).
### 01 | Adding Block to Entire Quilt Grid
First option is adding the same block to every cell block in the entire quilt.
1. Click on the infinity sign (∞) in the top left corner of the quilt grid.
* **Note:** All the cells are selected and are outlined in blue.
* 
2. In the BLOCKS tab, click on the **Add To Quilt** button next to the Sawtooth Star block.
3. Deselect the cells by clicking anywhere outside the quilt grid. The result is the same block in every spot on the quilt.

### 02 | Removing Quilt Blocks from the Quilt Grid
To remove a quilt block or multiple quilt blocks from the quilt grid:
1. Select the quilt block(s) you want to remove by **clicking** on them.
2. On the keyboard, press the **Delete** button.
* **Note:** You can also use the Back Space button to delete blocks.
3. The selected blocks have been removed and the corresponding quilt grid cells are now empty.

### 03 | Using the Selection Tool Button
Another option is to use the [*Selection Tool*](https://glossary.prequilt.com/pq-glossary/ss#selection-tool) button found on the vertical [*Toolbar*](https://glossary.prequilt.com/pq-glossary/ts#toolbar) to select cells blocks in the quilt grid. This has many options, so give them all a try. In this example, I'll showcase one of the checkerboard options.
1. *Starting with a blank quilt grid*, click on the **Selection Tools** button () on the vertical Toolbar.
2. Click on one of the selection options. In this example, I've selected **Checker Odd**.
3. In the BLOCKS tab, click on the **Add To Quilt** button next to the Sawtooth Star block.
4. Deselect the cells by clicking anywhere outside the quilt grid. The result is the same block has been added to a checkerboard pattern on the quilt.
