I designed this diamond nine patch quilt pattern with a fixed idea in my mind of where I wanted to create diamond shapes but not much idea of what to put in the rest of the quilt, so this really was a case of making it up as I went along. I am really pleased with the result and it is definitely a simple quilt to make – not a triangle in sight.The idea was for a main central black diamond shape with part diamonds in white lurking in the background.
I have used about 1/2 yard each of black and white and about 1 yard each of light blue and dark blue. The quilt finished size is 44″ by 48″.
black fabric: six 4.1/2″ squares, four 2.1/2″ strips cut across the width of fabric
white fabric: six 4.1/2″ squares, four 2.1/2″ strips cut across the width of fabric
dark blue: ten 2.1/2″ strips cut across the width of fabric
light blue: eight rectangles 4.1/2″ by 6.1/2″, nine 2.1/2″ strips cut across the width of fabric
I may have mis counted the numbers of 2.1/2″ strips as I was cutting them as I went along, but I hope that the above requirements are broadly correct.

Making nine patch quilt blocks
I used a bit of strip piecing to save time. Sew together 2.1/2″ strips of black/light blue and of white/light blue. Cut these at 2.1/2″ intervals to make strips of either black and light blue or white and light blue. You will also need to cut individual 2.1/2″ squares of both light blue and dark blue.
Place these strips and squares together in three rows of three with either a white diagonal or a black diagonal. I have placed a dark blue square in the alternate corners that aren’t either black or white, with a light blue square added in the middle row.
Sew the squares together across each row and then sew the rows together. Make sixteen black nine patch units and twenty white nine patch units. These are all 6.1/2″ squares.
Rows one and eight of the diamond nine patch quilt pattern
Make the corner units for the quilt with a white 4.1/2″ square and two dark blue rectangles – one 2.1/2″ by 4.1/2″ and one 2.1/2″ by 6.1/2″. Sew the 4.1/2″ rectangle to the top of the white square and then sew the 6.1/2″ rectangle to the side. You will need two of these for the first row of the nine patch quilt, but make four altogether.
The block at the middle of the first row is a 4.1/2″ black square with a 4.1/2″ by 2.1/2″ dark blue rectangle sewn to the top and two 6.1/2″ by 2.1/2″ dark blue rectangles sewn to the sides of the block. Make two of these.
Lay the quilt blocks out for the first row: corner unit, black nine patch, white nine patch, middle block, white nine patch, black nine patch and corner unit. Check the photo to see which way the black or white diagonals of the nine patch units should lie. Make two of these rows: the quilt is symmetrical and so rows one and eight are the same as each other. Row eight is row one turned upside down.
Sew the squares together across each row.
Rows two and seven of the nine patch quilt
For the second row you will need another different quilt block for the centre of the row. Cut a light blue rectangle 4,1/2″ by 6.1/2″ and sew a 6.1/2″ by 2.1/2″ dark blue rectangle to each side. Make eight of these although you only need one for this row.
The row is made using a black nine patch, white nine patch and black nine patch on each side of the central block. Again, check the photo to see which way the diagonal point. Make two of these rows – row two and row seven.
Rows three and six of the nine patch quilt
There is another quilt block to make for row three: a black 4.1/2″ square with a 4.1/2″ by 2.1/2″ dark blue strip across the top and a 6.1/2″ by 2.1/2″ dark blue strip on one side. Make four of these: two each for row three and row six.
Row three layout: one white nine patch, black square as shown on the right, white nine patch, light blue/dark blue block as made for row two, white nine patch, black square with two blue sides, white nine patch. Make two of these: row three and row six.
Rows four and five of the nine patch quilt
Just one more block to make for the middle of the quilt: cut a white 4.1/2″ square and sew one dark blue 4.1/2″ by 2.1/2″ rectangle to one side of the square. Make two of these.
Row four layout: black nine patch, white nine patch, light blue/dark blue block, white square as shown on the left, light blue/dark blue block, white nine patch, black nine patch. Make two of this row – row four and upside down for row five.
That completes the diamond nine patch quilt top. It is now ready for layering, quilting and binding.
