The chained nine patch quilt block is an old favourite.  It is obviously classified as a nine patch block and I have made it here as a 12″ square.

Cutting requirements for the chained nine patch quilt block

4.1/2″ squares:  two light green, two white

2.1/2″ squares:  eight white, four light green

2.7/8″ squares:  four each in dark green and white

Making the chained nine patch quilt block

Use the 2.7/8″ squares to make half square triangle units.  Place a dark green and a white square with right sides together and mark a line along the diagonal.  Sew a seam 1/4″ either side of the marked line and cut along the line.  this produces two half square triangle units which are both 2.1/2″ squares.

Press the seam allowance towards the green and trim the corners where the triangle tips stick out.

The chained nine patch quilt block layout is a simple six rows of six squares – that’s counting the 4.1/2″ squares as being equivalent to four of the smaller squares.  The large squares form a four patch unit in the middle of the block.  There is a 2.1/2″ light green square in each corner with a white square either side of each one.  There are two half square triangle units in the middle of each edge.  They are placed so that the two green triangles together form a larger green triangle pointing out from the middle.

Sew the squares together across rows one and six.  For the middle rows you will need to sew the smaller squares together in pairs vertically first and then sew the squares across the rows.  Finally sew the rows to each other to complete the chained nine patch quilt block.

Thanks for visiting my blog.

I hope to see you again soon.
