I didn’t intend this nine patch pinwheel quilt to end up the way it has done. I thought that I wanted to rotate it and sew the rows across the diagonal. In fact when I did that the quilt looked quite ordinary but I think that it looks stunning when sewn together in the conventional way. I have used 2 yards of red fabric and 3/4 yards each of black and white. The quilt measures 54″ square.
Cutting requirement for the nine patch pinwheel quilt
Black fabric: eight 2.1/2″ strips across the width of fabric, one 3.7/8″ square cut across the width
White fabric: eight 2.1/2″ strips across the width of fabric, one 3.7/8″ square cut across the width
Red fabric: fourteen 2.1/2″ strips cut across the width of fabric, five 6.1/2″ strips cut across the width
Making the pinwheel blocks
Cut ten 3.7/8″ squares from the 3.7/8″ strips in both black and white. Use these to make half square triangles. Place a black and white square with right sides together and mark a line along the diagonal. Sew a 1/4″ seam either side of the marked line to produce two half square triangles.
Make twenty half square triangles. Sew them together in pairs and the sew two pairs together to make a pinwheel. You will need five pinwheel quilt blocks.
Making the nine patch quilt blocks
Sew the 2.1/2″ strips of fabric together in threes. You will need three panels of black, red, black and three panels of white, red, white. You will also need two panels of red, white, red and two panels of red, black, red. Cut all these panels into 2.1/2″ strips.
Lay three strips out as shown – two black, red, black strips with a red, black, red strip between them. Sew the three rows together to make a nine patch unit. Make twenty four of these. Repeat with the red and white strips and make twenty four of them as well.
Cut the 6.1/2″ red strips at 6.1/2″ intervals to make squares. You need twenty eight.
Assembling the nine patch pinwheel quilt
I designed the quilt by putting a pinwheel quilt block in the middle and then working out from there. I used a round of red squares followed by a round of red and white nine patch units and then a round of red and black nine patch units. I’ll show you the rows as they are sewn because that will be easier for you to work from.
The first row has a pinwheel at each end with a red square in the second, fifth and eighth positions, a white nine patch in fourth and six positions and black nine patch units in third and seventh places. In the second and third rows you can see the diagonal lines forming.
Lines four, five and six are shown here. The pinwheel is in the middle of row five and you can follow the patterns of the nine patch quilt blocks easily enough.
Rows seven, eight and nine are the same as the first three rows, just the other way up.
Sew all the blocks together across each row and then sew the rows together to complete the nine patch pinwheel quilt. I haven’t added a border because I felt that it wouldn’t add anything to the quilt.
