## 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). *** ### YouTube Video *Coming soon...* *** ### 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** (![](https://667278489-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FPUFswdysHBJDPIJC9xe0%2Fuploads%2F2pQdYw3yn0w3jGirpIZM%2FClone.png?alt=media\&token=19516272-01c1-4426-adbf-2dcca0b50236)) 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** (![](https://667278489-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FPUFswdysHBJDPIJC9xe0%2Fuploads%2F2pQdYw3yn0w3jGirpIZM%2FClone.png?alt=media\&token=19516272-01c1-4426-adbf-2dcca0b50236)) 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.

*** ## Sewing Construction Diagrams No sewing construction diagrams necessary. Simply cut your square to size and it's a completed block unit ready to be used to create a larger quilt block.
