Exercise 02
02 | Create a custom Sawtooth Star block.
Objective | To create a quilt block from scratch. We call this a custom quilt block. We will be creating this Sawtooth Star block:
Did You Know | Custom quilt blocks are designed and created using the Block Editor, a pop-up window in PreQuilt.
01 | Create a New Custom Block
Click on the BLOCKS tab on the left side control panel.
Left Side Control Panel tabs Click on the Make Custom Block button.
The Block Editor window will open.
The Block Editor window
02 | Changing the Block Settings
The Block Editor has some options in the left side control panel that will help us recreate (or reverse engineer) our desired block - The Sawtooth Star.
Click on the Block Info tab.
Rename the block name to Sawtooth Star.
To stay organized, name your block Change both the horizontal and vertical gridlines to 4.
Note: The Sawtooth Star can be divided into 16 equal squares (4 columns and 4 rows). This information will help us know how many gridlines to set.
Ensure snapping is on - as a default it is turned on.
Note: If the circles are outlined, snapping is on. If the circles are not outlined, simply click on the buttons to turn snapping on.
03 | Create Quilt Block Pieces
Creating a quilt block in PreQuilt is much like piecing a block with fabric. To create our Sawtooth Star, we're going to use the different shapes beneath the Block Editor Canvas to create the different pieces of the block - squares, half square triangles (HSTs), and flying geese triangles.
