For the Diagonal Half Squares (or HST) you need:
Eight 3 3/8 inch squares of the white-on-white.
Four 3 3/8 inch squares of the black.
Two 3 3/8 inch squares of the black and white print.
Two 3 3/8 inch squares of the red
For the center strips you need four 5 1/2 by 2 1/2 inch strips of the white
and one 2 1/2 inch square of black.
First we will make the diagonal half squares (DHS) or half square triangles, which ever you prefer calling them. You can use which ever technique you want to make
them, but this is my favorite.
First, mark your white-on-white squares diagonally through the center. (This will be a cutting line when you are finished.) Place a red 3 3/8 inch square, right sides
together with the 3 3/8 inch marked white-on-white square. Sew on either side of the drawn line, exactly 1/4 inch from the first line. Cut this square in half on the
cutting line. Press to the darkest fabric, in this case red. You will now have two diagonal half-squares, which should measure exactly 3 inches. Repeat with the
remaining 3 3/8 inch squares. Press these all the same, to the darkest fabric and away from the white-on-white.
Make two sets like this and one set like this,
and one like this.
Now sew a white-on-white strip between a black unit and a print unit. Notice the direction the DHSs are pointing.
Next sew a white strip between a red and black unit. Again, pay attention to the direction your DHSs are pointing.

Your Handy Andy block should measure 12 1/2 inches.
I think it makes a pretty quilt all by itself, just by turning the blocks.
