Churn Dash quilt block instructions

Skill Level: Beginner

Grid: 3x3

The Churn Dash quilt block is fun to put together with just half square triangles, simple strip pieced squares and solid squares.

It makes a great block for quilting bee and guild exchanges—quick to whip up at the last minute if needed—because of its simplicity.

There are enough pieces in the block design to switch up the fabric placement and come up with radically different looking blocks.

This two fabric quilt block is known by a whole slew of other names. Do you recognize any of them? (Those underlined and blue are links to other tutorials on this website.)

Time to start stitching!

General Instructions

These abbreviations are used in this tutorial:

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

SA are 1/4" and pressed toward the darker fabric unless otherwise noted.

Pressing instructions are highlighted to make them easy to find.

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 patches for a Churn Dash

Sample Block Size: 6"(6-1/2" unfinished)

Grid Size: 2"

Two fabrics and simple piecing are all it takes for this block.

I prefer to starch my fabric before cutting. I find that both my cutting and piecing are more accurate that way.

I cut my HST patches a bit bigger than the dimensions in the chart, stitch the units and then cut them to size.

Perfect HST every time!

**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.

Step 2: Assemble the units

Half Square Triangle Units (HST)

We'll use the Quick Piece Technique for making HSTs.

Draw a diagonal line on the back of the 2-7/8" squares, dark enough so that you can see it.

With RST, align a light and a dark square and stitch a quarter inch away from the drawn line on both sides. Repeat for the second pair of squares.

Stitch on both sides of the line

The arrow points to my anchor cloth

Cut along the drawn line to create 4 HST units.

Press the units flat and then open with the seam allowance towards the dark fabric.

Use the table below to check the accuracy of your HSTs. Trim to size if needed.

HST Dimensions

Block Size
Trim HST to…
3" 1½"
4 1/2" 2"
6" 2½"
7 1/2" 3"
9" 3½"

For more detailed information on making Quick Pieced HSTs go to HST: Technique #1.

Strip Sets

With RST, align the long edges of the light and dark 1-1/2" x 11" strip and stitch.

Stitch the strips together

Press the strip set flat and then with the SA towards the dark strip.

With your rotary cutter and ruler, straighten one end of the strip set.

Straighten one side of the strip set

Align a straight line on the ruler with the seam line, and
cut off the uneven edge on one short side of the strip set.

Then cut four 2-1/2" squares from it.

Sub-cut the strip set into four sections

Again, align a straight on the ruler with the seam line before sub-cutting.

Step 3: Assemble the Churn Dash quilt block

Lay out the HSTs, strip pieced units and solid squares into the Churn Dash design. 

Lay out the patches for your Churn Dash

Stitch the units in each row together.

Press, with the seam allowances away from the HST so that your seam allowances nest. That makes matching easier.

Press the seam allowances in the direction of the red arrows below.

Variations on a Churn Dash design

There are several variations of the simple 3x3 Churn Dash quilt block.

All involve a change in the fabric placement. Many radically change the look of the block.

Greek Cross quilt block

A two fabric block with some swapping of the placements. A totally different look.

Two different fabrics are added to the original Churn Dash in the corners.

Grecian Design quilt block

Grecian Design

This 3 fabric block looks nothing like the original, but all the design lines ARE there.

This version is also called: Grecian Square, Grecian or Greek Square.

Mosaic quilt block


Add a fourth fabric and the block changes even more.

Then there are those that keep the same basic structure, but alter one of the elements.

Prairie Queen quilt block

Prairie Queen

This quilt block has four patches instead of strip pieced squares in the center of each side. This small change adds a lot of movement to the block without increasing the difficulty.

Crow's Nest quilt block

A third strip is added to the strip pieced squares creating a more delicate looking block.

For a rotary-cutter friendly block, make sure you choose a finished grid size that is easily divisible by 3.

Monkey Wrench quilt block

Monkey Wrench

In this last block, the Churn Dash design is drawn on a 5x5 grid (sometimes called an uneven 9-patch). The center and center side units are now a quarter the size of the HSTs.
