The Havana Cathedral quilt is based on a gorgeous stained glass window that I saw in the Cathedral when I was in Cuba recently. I had intended to make a wall hanging, but somehow I’ve ended up with a queen size quilt pattern! Each block is easy to make and they are big blocks so the quilt goes together quite quickly. It’s also rectangular and would fit a queen size bed, so it ticks a lot of boxes.

Within the quilt I have used three blocks which are 18″ by 24″ finished size and six blocks which are 24″ squares. The fabric requirements are 2 yards each of dark blue and red, 1.3/4 yards of light blue, 3/4 yard of white and 1/2 yard of medium blue. You can buy these fabrics at a discount in this week’s special offer.

### Cutting requirements for the Havana Cathedral quilt

12.7/8″ squares: twelve light blue, six red, six dark blue

4.3/4″ squares: twelve medium blue

3.1/2″ squares: twelve dark blue, twelve white

3.7/8″ squares: eighteen each in dark blue and red, twelve each in light blue and red, six each in red and white. These are for the half square triangles. In addition you will need six dark blue, six white and twelve red squares for the diamond in a square blocks.

For the borders you will need to cut seven strips across the width of fabric in each of 2.1/2″ red, 1.1/2″ white and 2.1/2″ dark blue.

### Make half square triangle units

You need to make half square triangles with some, but not all of the 3.7/8″ squares. Use those squares listed in pairs above.

Place a red square right sides together with either a light blue or a dark blue square. Mark a line along the diagonal and sew a 1/4″ seam either side of the marked line. Cut along the line to produce two half square triangle units. These are now 3.1/2″ squares.

### Make diamond in square units

Cut the remaining 3.7/8″ squares along one diagonal to create two triangles from each square (shown in the top right of the photo).

Lay down a 4.3/4″ medium blue square and place a dark blue and a white triangle on two opposite edges, with two red triangles on the other two opposite edge.

Sew the dark blue and white triangles to the edges of the square first.

Press them open and then sew the two red triangles to the square. When you press these open you’ll see that you have created a square with a medium blue diamond in the middle. Trim the middle of each edge where the triangle tips stick out. This is now a 6.1/2″ square.

### Make the Havana Cathedral quilt block

This block is made of eight rows of six squares each – that’s counting the diamond in square units as equivalent to four squares.

I’ve shown the top four rows first. In each corner place a dark blue square with a dark blue/red half square triangle beneath it. In the middle place two diamond in a square units. Lay them with the red triangles in the top middle to create a larger red triangle pointing downwards.

The third and fourth rows are made with dark blue/red half square triangles at each end and a light blue/red half square triangle inside them. In the third row there are two white squares in the middle. For the fourth row place two red/white half square triangles in the middle.

The lower half of the block is very similar. Rows five and six are almost the same as rows three and four. Just check which way to place the half square triangles.

Rows seven and eight are almost the same as rows one and two. Again it is just the direction of the triangles that has changed.

Sew the squares together across each row. You need to make a double row at the top and bottom of the block.

Sew the dark blue square and red/dark blue half square triangles together first. Then you can sew them to the diamond in a square units.

Sew the rows to each other to complete the block. It measures 18.1/2″ by 24.1/2″ at the moment. You need to make three of these.

### Make the alternate block

This is a huge block, but I felt that it gave the right feel to the surrounding area of the Havana Cathedral blocks. It’s also dead easy to make!

Use the 12.7/8″ squares to make half square triangle units. Use exactly the same method as above for the smaller half square triangle units.

Place two red/light blue half square triangles with two red/dark blue half square triangles as shown. This makes one large red triangle, one large dark blue triangle and two large light blue triangles. Sew them together in pairs and then sew the pairs together to create the block. This is now a 24.1/2″ square and you need to make six of them.

As an aside, I had originally intended to make these blocks 18″ by 24″, same as the other blocks. However the triangles were very odd sizes for this, so I opted for simplicity and made the blocks as squares instead.

### Assemble the Havana Cathedral quilt

Sew the blocks together in three rows of three. Place the Havana Cathedral block in the middle of each row.

In rows 1 and 3 place the alternate blocks on either side with the dark blue triangle on the inside.

For row 2 the alternate blocks are rotated so that the light blue triangles lie on the inside.

On the left hand side the red triangle lies at the top while on the right hand side the blue triangle lies at the top.

Sew the blocks together across each row and then sew the rows to each other.

### Add the quilt border

I’ve used three borders to frame the quilt. Make the first border with 2.1/2″ red strips. Cut two lengths of 66.1/2″ for the top and bottom together with two lengths of 76.1/2″ for the sides.

The second border is made with 1.1/2″ strips of white fabric. Two lengths of 70,1.2″ for the top and bottom and two lengths of 78.1/2″ for the sides.

Finally make the third border with 2.1/2″ strips of dark blue. Two lengths of 72.1/2″ for the top and bottom with two lengths of 82.1/2″ for the sides.

That completes the Havana Cathedral quilt top. It is now ready for layering, quilting and binding. Full details of these steps can be found in the beginner quilting section.

One of the colour combinations that I love in quilts is purple and green. Yesterday I visited a National Trust property with a wonderful garden. These iris flowers were a gorgeous deep purple – just as beautiful as the fantastic William Morris designs within the property.

The house itself was Wightwick Manor which is a celebration of the Arts and Crafts Movement – absolutely beautiful both inside and outside.
