Friendship Chain Quilt Block Pattern

I’ve made the Friendship Chain quilt block as a 12″ square finished size.  The block makes up easily – pretty in its own right and also useful as an autograph quilt block.  Use the diamonds in the middle of each block for signatures.

The block is made entirely with half square triangles.

Cutting requirements for the friendship chain quilt block

3.7/8″ squares:  eight blue, eight white

Make the half square triangle units

Use all the squares to make half square triangle units.  Place a blue and a white square 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 produces two half square triangle units which are now 3.1/2″ squares.  Trim the two corners where fabric sticks out.  This helps reduce bulk in the seams.

I’m showing the outer frame first because I think it’s much clearer to see how this frame is laid out when there’s nothing else to distract your eye.

Place the squares with the blue triangles forming larger triangles.  Lay one pair on the top with the blue triangle pointing up, another at the bottom with the blue triangle pointing down.  Down each side place two pairs of squares with the larger blue triangles pointing in towards the middle.

Now add the four squares in the middle.  Place these so that the white triangles form a diamond.

Sew the squares across each row and then sew the rows to each other to complete the block.

Friendship Chain quilt ideas

The basic quilt shown here uses sixteen blocks laid out in four rows of four.

This makes a 48″ square quilt (without the borders).

Use red for alternate blocks

As an alternative I tried making alternate blocks with red instead of blue.  This definitely makes a more interesting quilt.

Thanks for visiting my blog.

I hope to see you again soon.

    Love this pattern Rose. Looks like an easy one to put together and the white and blue is so fresh looking. Blue and white is always a winning combination to me. This is definitely on my to do list for a dear friend. Thanks Rose.
