Quilt Block: Fools Square Quilt Block

By Alanda / February 15, 2017

I really like  how this square comes together. I did start out doing the centre checkerboard in the usual way by cutting the strips of fabric across the width of fabric. But decided that as I was only making the two squares it was just as easy to cut the fabric into the squares required.

I have just used 2 contrasting fabrics because I think it shows the pattern off nicely. But as always you can use as many colours as you wish.

Note: All seams are sewn with a ¼” seam allowance.

These instructions make a 10″ block.

What You Need:

Fabric 1 (white):

  • 8 squares @ 2½” x 2½”
  • 6 squares @ 3″ x 3″

Fabric 2 (green):

  • 5 squares @ 2½” x 2½”
  • 6 squares @ 3″ x 3″

What to Do:

Make up the centre block first.

  • Take the 2 ½”squares and lay out in a checkerboard pattern as per the image below.
  • Place the first two squares in row 1 one on top of the other with right sides facing.
  • Sew the squares together with a ¼” seam.


  • Add the next square to the first two with right sides facing
  • Sew the squares together with a ¼” seam.
  • Sew the other two rows in the same manner.

Sew the rows together.

  • Place the top row on top of the next row down, right sides together
  • Sew the rows together with a ¼” seam.
  • Do the same for the last row.


  • Press the seams as shown below.


  • Put the centre piece aside.

Make the Half Square Triangles.

  • Take one 3″ square (white).
  • Draw a line on one piece, across the diagonal from corner to corner.
  • Place on top of a contrasting coloured (green) square and neatly match up the edges.
  • Pin to hold in place.


  • Sew a seam line ¼” on either side of the drawn line.


  • Slice the square across the diagonal on the drawn line.


  • This gives you 2 half square triangles.


  • Press the seams to the dark side.


  • Trim the half square triangles to 2½”. If you  are unsure of how to do this here is a link to our video on how to do it.


Lay out the pieces to form the pattern.


  • Sew the side pieces together. Place the top square on top of the next square and sew together,


  • Sew the last square to the other two squares
  • Do the same with the other side pieces.


  • Sew the side pieces to the centre piece.


  • Press the seams towards the centre.


  • Sew the top and bottom rows in the following manner.
  • Place the first two squares one on top of the other, right sides together and sew with a ¼” seam.
  • Do the same with the last two squares in the row


  • Sew the middle square to the first two squares that you have sewn together.
  • Right sides together.
  • Then sew the last two squares to the middle square.
  • This forms the top row.
  • Repeat the process for the bottom row.


  • Press the outside seams towards the outer edge.
  • Press the middle seams towards the centre.
  • See photo below.


  • Sew the top and bottom rows to the centre block.
  • Lay the top row over the centre block, right sides together.
  • Sew with a ¼” seam.
  • Repeat with the bottom row.


  • The Fools Square quilt block is now finished.
