Shoo Fly is another block made of simple shapes that we've already visited: squares and half square triangles (HSTs).
For a 12" finished block you'll need:
(4) 4-1/2" light squares
(1) 4-1/2" dark squares
(4) 4-1/2" HSTs, light and dark (You know the drill, start with 4-7/8" squares, cut in half diagonally, etc)
Arrange as below; couldn't be easier, right?
Rotating this block doesn't give you different designs because it's bi-directionally symmetrical: no matter which way you turn it, it shows the same face on all sides. But it is a fun one for diagonal set, and setting with alternate blocks. A few examples are below; what else can you put together in Bock Fab?
