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:

  • Simplicity
  • Fence Row Quilt
  • Eight Cornered Box

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.





General Instructions


Sample Block Size: 4-1/2"

Several abbreviations are used in this tutorial:

  • SA - seam allowance
  • RST - right sides together
  • HST - half square triangle


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 Shoofly patches

All it takes are two fabrics. Just be sure there's enough contract between the two.

**I prefer to cut my patches extra large for HST, stitch, and then trim them to size. If you prefer to do the same, add a bit extra to the measurements for Patches #1 and #2 above.

There is a chart further down in these instructions where you need it for trimming them to size.


These are some of the supplies I use to prepare and cut my fabric patches.



These are the cut patches.

Step 2: Assemble the units


Half Square Triangles

Make 4

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 #1s with a pencil just dark enough to see.

With RST, layer a #1 and #2 together and stitch 1/4" away from 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 HSTs.


Cut the HSTs apart on the drawn line


Press.

Find your finished block size in the chart below and the corresponding HST dimensions. Trim as needed.

7 1/2" 3"

Your half square triangles look like this.

Step 3: Assemble your Shoo Fly block


Lay out your patches in rows to create the Shoofly design.


Lay out the sewn units and cut squares


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.

Common Variations on a Shoofly Quilt Block


The unifying element in each is a HST in each corner.

Two colors form the snowball with a third fabric, a background, finishes out the corners.



Snowball Variation

This time with just two fabrics with dark corners and center.

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.
