The Kings Crown quilt block is a striking block – one that you know will look good in a quilt. I’ve made it here as an 18″ square finished size.
Cutting requirements for the Kings Crown quilt block
3,1.2″ squares: four blue
6.1/2″ squares: one white (or you could use four 3.1/2″ white squares)
3,1.2″ by 6.1/2″ rectangles: four blue
3.7/8″ squares: ten blue, ten white
Making half square triangle units
Make half square triangle units with the 3.7/8″ squares. Place a blue and a white square with right sides together and mark a line along the diagonal. Then 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 blue and trim the two corners where the triangle tips stick out. (I know the colours in the photo are wrong, but I forgot to take a photo of this stage when I was making the block).
Making the kings crown quilt block
Lay the squares out as shown. In fact, this would be six rows of six if I had used only 3.1/2″ squares. As it is, I doubled up a bit in some places to reduce the number of seams.
The first and sixth rows have a blue rectangle at each end with a pair of half square triangles in the middle.
The second and fifth rows are made with a blue square at each end and four half square triangles between them.
The third and fourth rows are made with the white square in the middle and a four patch of half square triangles on each side.
Another way to consider the layout is to treat it as a series of four patch units: Each corner is made of a blue rectangle on one line and a blue square and half square triangle on the other line. These are placed so that the blue rectangle is always on the outside. Between each pair of corners there is a four patch unit made with four half square triangle units. These are placed so that the white triangles form that white diamond frame.
Sew the squares together within each four patch unit and then sew them together to make three rows. Sew the rows to each other to complete the kings crown quilt block.
I became a little carried away when I was looking at quilt ideas using this block.
The first idea shows sixteen blocks sewn together in four rows of four.
For the second idea, I reversed the colours in some of the blocks.
The ones with a blue background have been placed in the middle and in a diamond formation. I rather liked this idea – plenty to look at.
For the third idea I have included one block with red in it for those of you would prefer to make it as a red, white and blue block. As you can see, I have used red for the central square and the outer frame, with one frame each of blue and then white around the red square.
Thanks for visiting my blog.
I hope to see you again soon.
