## Square Block Unit in PreQuilt
**Squares** are really the easiest block units in PreQuilt.
And since the idea behind this series is to build a block unit (not an entire block that is just a square), I'm going to create a 12" finished block that is made up of only square block units (like for example, the **Nine Patch** quilt block).

### Help Guide
1. Click on the **BLOCKS tab** on the left side control panel.
2. Click on the **Make Custom Block** button.
3. The **Block Editor panel** will slide out and overtake your screen. My block is set to 12" x 12" finished, but it doesn't matter, the next steps will work for all sized blocks.
4. Set your grid guidelines by changing the number for the horizontal and vertical units.
* Since I'm going to be creating a **Nine Patch** quilt block, I'll set my gridlines to 3 horizontal and 3 vertical units.
5. Click on the **square shape** () from the central control panel.
6. One square will be added to the block space. Done, we now have a square block unit!

7. To continue building the Nine Patch block, click on the **Clone button** () on the central control panel.
8. **Move** the new square block unit so it starts forming the Nine Patch block.
9. **Repeat** Steps 7-8 until you have all the orange block units for our Nine Patch block.

10. Click on the **Clone button** () on the central control panel.
11. Click on the **Link button** for a different fabric link (so that there are now 2 different fabrics being used). In this example, I am using Fabric Link B.
12. **Move** the new square block unit into one of the empty spots.
13. **Clone** and **move** 3 more blue square block units until the Nine Patch is completed.
