QST unit fun

Quarter Square Triangles with Plain Squares

What scraps it uses:

• 4" squares (for the plain squares - cut to 3.75")
• 5" squares (for the QST units - one each in two contrasting colours - makes 2 units)

I make the QST units by putting two squares face together, drawing a line diagonally across the back and stitching 1/4" from the line on both sides. Then cut them apart, press, and put them back together faces towards and do it again. Web directions for that method can be found lots of places, for instance, here.

You can actually use any size squares you like, but the squares for the QST units need to be 1.25" bigger than the size you desire, so your plain squares need to be 1.25" smaller than the ones you choose for the QST units. If you are unsure, make a single pair of QST units and check what size they are, then cut your plain squares to that size!
