November BOM (make in October, bring to November meeting)


November BOM is made with a dark blue, a light, icy blue and white.  Please use fabrics that read as a solid.  The white can be either a solid or a white on white, but please, no ecru, beige, natural, off-white, etc.  Also please try to stay away from the greenish-blues & turquoises.

This block is called Margaret’s Choice.  It will be a 10″ finished block, so your completed block should measure 10.5″

Margaret’s Choice is made up of half square triangles in a 16 patch setting.  Each patch measures 2.5″ (finished).  Typically to make a 2.5″ half square triangle you would start with squares that are 3 3/8″.  It has been my experience that using that exact measurement rarely gives me a perfect half square triangle unit so we decided to make the squares bigger and trim them down to the correct size.  If you prefer to start with a 3 3/8″ square, you are most welcome to do so.  Be sure to trim the triangle units to 3″ so they will finish at 2.5″.

So…..we begin by cutting 4″ squares.  You will need 6 dark blue, 4 light ice blue and 6 white.


Your squares will be paired up as follows:

2 dark blue/2 light ice blue

2 light icy blue/2 white

4 dark blue/4 white


Using a pencil and ruler, draw a diagonal line on the wrong side of the lightest square of each pair.  Then place each square with it’s partner, right sides together.

Stitch 1/4″ from both sides of the drawn line.

Cut the two triangle units apart on the drawn line.

Open the triangle units and press toward the darker fabric.  Trim each unit to 3″.

Lay the units out as shown below and sew into rows.

Press the seams in each row in opposite directions so the seam allowances will “nest” together as you sew them together.

Your finished block should look something like this.
