# QST: 4 Different Fabrics

## <mark style="color:blue;">QST Block Unit in PreQuilt</mark>

A common **Quarter Square Triangle** block unit is often composed of 4 different fabrics and can have a very scrappy look to it.

And since the idea behind this series is to build a block unit (not an entire block that is just a quarter square triangle), I'm going to create a 12" finished block that has a quarter square triangle block unit in it (like for example, the **Card Trick** quilt block).

1. Click on the <mark style="color:blue;">**BLOCKS tab**</mark> on the left side control panel.

2. Click on the <mark style="color:blue;">**Make Custom Block**</mark> button.

   <div align="left"><figure><img src="https://667278489-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FPUFswdysHBJDPIJC9xe0%2Fuploads%2FEp85lfXPh1t2HyDeRFSt%2FScreen%20Shot%202022-09-28%20at%203.47.18%20PM.png?alt=media&#x26;token=f16698cc-cee6-4b9b-aa75-77a209b9b7e3" alt=""><figcaption></figcaption></figure></div>
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.

   * In this example, I'd like to create the **Card Trick** quilt block, so I'll set my gridlines to 6 horizontal and 6 vertical units.
   * Note: I set 6 horizontal and 6 vertical (instead of 3), because I need to have a gridline for the midpoint of each QST.

5. Click on the <mark style="color:blue;">**isosceles triangle shape**</mark> (<img src="https://667278489-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FPUFswdysHBJDPIJC9xe0%2Fuploads%2FHYI0J0BLERsnpFcOKDr9%2FScreen%20Shot%202024-10-31%20at%204.53.58%20PM.png?alt=media&#x26;token=0a3532f3-9f96-46c1-b472-a6bf2438af56" alt="" data-size="line">) from the central control panel.
6. One isosceles triangle will be added to the block space. <mark style="color:blue;">**Move**</mark> it into the correct position by clicking on the shape on the block space and moving it to where it belongs.

7. Now that the isosceles triangle is in place, we can now stretch it into the shape of a quarter square triangle. With the triangle selected, grab the square on the right side of the isosceles triangle and drag it until the triangle fills the width of two grid spaces. If the snap to grid is turned on (default) then the shape will automatically fill the grid space.

   * Keep in mind this is only quarter of the block unit, the three quarters are empty (denoted by gingham background).

This method makes 1 QST block unit at a time. But these instructions give you enough fabric to produce 4 QST units. But each QST block unit is made independently.
