Big Dipper - a four patch block

Although this block looks simple (four quarter square triangle units mounted together) it uses a lot of bias edges, this means it is prone to stretching if your not careful.  You have been warned!
Drafting is easy start with a two by two grid.

Draw diagonal lines so that each square is divided into four diagonally.

Here is a video by quilt codex for a single block
