Quilt Block: Fools Square Quilt Block

fools-square-quilt-block,quilting,craft, sewing

I really like how this square comes together. I did start out doing the center checkerboard in the usual way by cutting the strips of fabric across the width of the 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.

Watch the video tutorial below or scroll down for the written instructions

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

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

These instructions make a 10″ finished 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″
