The California Chimney quilt block is a delight – easy to make and using three different shades of blue with white. It is classified as a five patch block and I have made it here as an 18″ square finished size.
Cutting requirements for the California chimney quilt block
6.1/2″ by 3.1/2″ rectangles: four white, two medium blue
3.1/2″ squares: four white, four medium blue
3.7/8″ squares: two each in light blue and white, two each in light blue and dark blue, four each in light blue and medium blue
Make half square triangle units
Use the 3.7/8″ squares to make half square triangle units in the colour combinations listed above. Place two squares with right sides together and mark a line along the diagonal. Sew a 1/4″ seam either side of the marked line and cut along the line. This will produce two half square triangle units which are now 3.1/2″ squares. Press the seam allowances towards the darker fabric and trim the two corners where fabric sticks out.
Make the central section
I’m showing the central area first. This is a more simple way of seeing the layout and all the half square triangles are used up in this section.
Place the four dark blue/light blue half square triangles in the middle. Make sure that the dark blue triangles form a diamond in the middle of the block.
On each edge of this central area place two medium blue/light blue half square triangles. Make sure that the medium blue triangles form a larger triangle pointing towards the middle. In each corner of this section place a light blue/white half square triangle with the white on the outside, forming the corner of the section.
California chimney quilt block full layout
For the full layout you now need to add just one more frame. The top and bottom rows are made with a 6.1/2″ medium blue rectangle in the middle and a white rectangle on either side.
For the sides, place two medium blue squares in the middle of each edge with a white square on either side.
I have chosen to use rectangles in the top and bottom rows but pairs of squares down the sides purely to simplify the sewing. This way it is straightforward now to sew the pieces together across each row and then sew the rows to each other to complete the quilt block.
California chimney quilt ideas
For the basic quilt design I have shown nine blocks sewn together in three rows of three.
As an alternate design I have simply added one green square in one corner of each block. I was quite surprised at how much difference this made to the overall look of the quilt.
