Triplet Quilt Block

The triplet quilt block is attributed to the Kansas City Star and is a nine patch block.  I have made it as a 9″ square.  It is usually made in red and white but I’ve made it in blue because I happened to have plenty of blue squares in my fabric stash.  I think that this one would make a spectacular quilt border.

Don’t be put off by the quarter square triangles – they are just one step on from half square triangles.

Cutting requirements

3.1/2″ squares:  four blue, two white

4.1/4″ squares:  two blue, thwo white

How to make the triplet quilt block

For the quarter square triangle units you need first to make half square triangles, so place a blue and a white 4.1/4″ 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 to produce two half square triangle units.

Press the seam allowances towards the blue fabric and trim the corners.

To make these into quarter square triangles you just need to do the same thing again.  Place two of the half square triangles with right sides together, making sure that the white of one square is placed facing the blue on the other one.  Mark a line along the diagonal that crosses the seam and sew a seam 1/4″ either side of the marked line.  Cut along the line and you will produce two quarter square triangles for each pair of half square triangle units.  These are now 3.1/2″ squares.  You should now have four of these although you only need three for the triplet quilt block.

Lay the squares out in three rows of three.  The three quarter square triangles form the middle row.  In two of them the white hourglass shape is vertical while in the middle one the white hourglass is horizontal.

The four plain blue squares are placed in the corners with the white squares in the remaining two places.

Sew the squares together across each row and then sew the rows together to complete the triplet quilt block.

Thanks for visiting my blog.
