How To Make The Half Square Triangle Units

Pair the light squares with the coloured squares right sides together.

Draw a diagonal line on the back of the lighter of the two fabrics from corner to opposite corner.

Sew seams ¼ inch either side of the line. 

Cut in half along the drawn line.

Press open and trim to 4 ½ inch squares.

Line up the squares as in the picture, sew the squares together to form the rows, press the seams open.

(You can change the design if you prefer by placing your HST’s in a different arrangement. Play about and see what patterns you can make!)
