The double star quilt block is surprisingly easy to make – only two colours and it’s made from squares, rectangles and half square triangles only. It is a big block, though. I have made it here as a 30″ square finished size, but you could make it as a 20″ square using 2.1/2″ and 2.7/8″ squares instead. In the size that I have made it, it just needs a few borders to become a lap quilt or a Linus quilt.
Cutting requirements for the double star quilt block
3.1/2″ squares: twelve white
3.7/8″ squares: twenty red, twenty white
3.1/2″ by 6.1/2″ rectangles: six red
9.1/2″ squares: four white
Make the half square triangles
Use the 3.7/8″ squares to make half square triangle units. Place a red and a white square 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 red and trim the two corners where fabric sticks out.
Make the central star block
Lay the squares out in four rows of four.
Place two rectangles in the middle with a pair of half square triangles on each edge. Lay the half square triangles so that the white triangles lie together, forming a larger white triangle pointing towards the rectangles.
Add a 3.1/2″ white square in each corner.
Sew the squares together across the top and bottom rows. For the middle row you need to sew the two half square triangles together first and then you can sew the pieces together across the row.
Sew the three rows to each other.
Make the part star sections
The parts stars are obviously very similar to the full star block. Lay the pieces out in three rows of four, using just one rectangle rather than the two used in the full star block. Arrange the half square triangles in pairs around the rectangle. Note that there are white squares in the first row only.
Sew the squares together across each row and then sew the rows together.
You need to make four of these part star blocks.
Assemble the double star quilt block
This last bit is easy: lay the blocks out in three rows of three. Place a 9,1/2″ white square in each corner with the full star in the middle. Lay one part star on each edge of the central star. Rotate them so that the white corners are always on the outside.
Sew the blocks together across each row. Note that the rows are different heights: the first and third rows are 9.1/2″ high while the second row is 12.1/2″ high. Sew the rows to each other to complete the quilt block.
Double star quilt suggestions
When the block has been made this large, it doesn’t need much to make it into a quilt. For my first quilt suggestion I have just added three borders to the block.
The first and third borders are 3″ wide while the middle border is 1″ wide.
As an alternative I have added large half square triangles around the block to give it more of a frame.
These half square triangle units are made from both 4.7/8″ and 9.7/8″ squares.
