Browsing through the star blocks in BlockBase and Electric Quilt Chris came across a star called Star and Dot which looks a bit like a Blazing Star with bits missing. Further browsing produced a few more stars in the same family.
Let’s start with Star and Dot
Then add a few lines to make New Star
Or add spiked corners to make Blazing Star
Split those corners to make another version of Blazing Star
Change the corner and centre to make the Emerald block
Or add in lots of extras to make Optical Illusion
You can download the cutting instructions for all these blocks (12 inches) and blank blocks to colour here. You could also use the blank Star and Dot block to design a block of your own.
