Shoofly quilt block tutorial

Skill Level:  Beginner

Grid:  3x3

The Shoofly quilt block is a terrific block for the beginner quilter because it contains only half square triangles and cut squares.

A cameleon quilt block because several are based on this very simple structure.

You may know this block by one of several other names:

Fence Row Quilt
Eight Cornered Box
Fifty Four Forty or Fight
Hole in the Barn Door

Click the underlined names above for more traditional versions of the block.

On this page you'll find the instructions to make this block in 5 different sizes, along with several variations on the design itself.

Construction Instructions

Block Size: 4-1/2"

Grid Size: 1-1/2"

All seam allowances (SA) are 1/4".

When you are instructed to press, first press the pieced unit flat to set the seam. Then open the patch, pressing from the front. Seam allowances are pressed to the dark fabric unless otherwise noted.

Step 1: Cut the fabric patches

Four 2" squares

One 2" square

Step 2: Assemble the units

Half Square Triangles

Use the Quick Pieced technique to make these units. (Click here for more detailed instructions for this technique.)

Draw a diagonal line on the backs of the two light 2-3/8" triangles with a pencil just dark enough to see.

With RST, layer a dark and a light large square together and stitch on both sides of the drawn line. Repeat for the second pair.

Stitch on both sides of the drawn line

The arrow points to an anchor cloth.

Cut the patches apart on the drawn line to create 4 half square triangle units.

Cut the HSTs apart on the drawn line


Trim to size—2-1/2" square.

Your half square triangles look like this.

Step 3: Assemble the block

Lay out your patches in rows.

Stitch the units in each row together.

Press flat to set the seam and then SAs toward the solid square. (See the arrows in the diagram below.

Press the seam allowances away from the HST

Stitch the rows together. The SAs nest to help make matching them pretty easy. Do use pins if you need them.

Grandmother's Choice

This Shoofly quilt block is drawn on a 5x5 grid, sometimes called an uneven 9-patch. Still a two fabric block the corner units are twice as wide as the side center units.

Big O

This two color block changes up the construction just a bit. Four rectangles with connector corners are puzzle pieced around a center square using a piecing technique called 'partial seams'.

We used this piecing technique in the Double Star Quilt Block.
