The Split Quarter Square Triangle block unit is a hybrid of a Half Square Triangle block unit and a Quarter Square Triangle block unit. One diagonal half of the square is made up of a half square triangle and the other diagonal half of the square is made up of 2 different quarter square triangle pieces.
Typically Split QSTs use 3 different fabrics, but there are some interesting designs that use the same fabric for the half square triangle piece and one of the quarter square triangle pieces.
And since the idea behind this series is to build a block unit (not an entire block that is just a Split QST), I'm going to create a 12" finished block that has a Split QST block units in it (like for example, the Card Trick quilt block).
Click on the BLOCKS tab on the left side control panel.
Click on the Make Custom Block button.
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.
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.
One half square triangle will be added to the block space. Move it into the correct position by clicking on the shape on the block space and moving it to where it belongs.
Now that the half square triangle is in place, we can now scale it so that it takes up half of the square. With the triangle selected, grab the small square on the top right side of the half square triangle and drag it until the triangle fills the width of two grid horizontal and two vertical grid spaces. If the snap to grid is turned on (default) then the shape will automatically fill the grid space.
NOTE: If the snap to grid is turned on (default) then the shape will automatically fill the grid space.
Keep in mind this is only one half of the Split QST block unit, the two quarters are empty (denoted by gingham background).
Click on the Link button for a different fabric link (so that the new QST block piece is now linked to a different Fabric Link). In this example, I've linked them to Fabric F.
Move it into the correct position by clicking on the shape on the block space and moving it to where it belongs.
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 equilateral 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.
Click on the Link button for a different fabric link (so that the new QST block piece is now linked to a different Fabric Link). In this example, I've linked them to Fabric D.
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.
Click on the half square triangle shape () from the central control panel.
Click on the isosceles triangle shape () from the central control panel. One isosceles triangle will be added to the block space.
Click on the Rotate button () on the central control panel so that it is in the correct orientation. You will need to click on the Rotate button several times to get it to be upside down.
With the quarter square triangle shape selected, click on the Clone button () on the central control panel.
Click on the Rotate button () on the central control panel so that it is in the correct orientation and move it into the correct position. You will need to click on the Rotate button several times to get it to be upside down.
