This time we are using the rotary cutter for all the shapes.
To cut squares to make half square triangles you need to add 7/8" to the finished size of the unit, that is 4 7/8" for a 4" finished unit. Cut once from corner to corner.
To cut squares to make quarter square triangles you need to add 1 1/4 " to the finished size of the unit, that is 5 1/4" for a 4" finished unit. Cut twice from corner to corner.
For squares add 1/2" that is 4 1/2" for a 4" finished unit.
To make a block like this you need a 4 1/2" centre square, four 4 1/2" corner squares, two 4 7/8" squares for the half square triangles and one 5 1/4" square of each of two fabrics for the quarter square triangles.
