Friendship Star quilt block

green and pink friendship star quilt block with title.

Friendship star is the first block in the Twinkle Sampler Quilt, but it can also be used on its own. It is one of the easiest star blocks to make.

This block is just a variation of a nine-patch block, so it is easy to put together. These instructions are for a 12″ finished block, but you can easily adjust to other sizes.

Fabric requirements

You will need:

  • four 4-1/2″ squares background fabric
  • one 4-1/2″ square feature fabric
  • four 4-1/2″ half-square triangle units of background and feature fabric

Feel free to use your favourite method to make the half-square triangle units. I recommend the Most Popular Method for making half-square triangles . This method makes two units at a time, it is easy, it is accurate and it doesn’t waste a lot of fabric. Remember that the finish size in the block is 4″, so these HSTs will be 4-1/2″.

fabric pieces laid out for friendship star quilt block.

Layout the pieces as shown in the picture.

Pay special attention to the direction of the half-square triangles, since it is easy to get them turned the wrong way. Notice that the top and bottom seams are parallel and the left and right seams are parallel, but they are different directions from each other.

Block assembly

The pieces are assembled just like a traditional nine patch block.

joining squares for friendship star quilt block.

Begin by joining two of the squares from each row with a 1/4″ seam allowance.

Press the seams toward the solid fabric squares – away from the half square triangles. Press this way regardless of what fabric is light and what is dark. This takes some of the bulk out of the seams by not having the triangle seam pressed back on itself.

Add the third square onto the rows.

Before adding it, be sure to lay out the pieces to make sure nothing has been turned around during assembly.

two rows joined for friendship star quilt block.

Join two of the rows together.

Because the seams of the rows were pressed to the plain fabric squares, the seams from the top row will be pressed in the opposite direction to the seams in the middle row. That will help them go together nicely, because they will naturally interlock.

This block should be 12-1/2″ square. When it is joined with other pieces, it will be 12″ square.
