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

and here the quilt behind is the Big Dipper block set on point with sashings.

This one is from Sew Granny Sew and uses three colours rather than two
