The Churn Dasher quilt block is made all of half square triangles and cut squares.

It's a good block for the beginning quilter to try out a method for making half square triangles eight at a time. A great technique for every quilter to have in their 'piecing arsenal'!

Churn Dasher Quilt Block Pattern tutorial

The block design lends itself to a number of variations. You'll find a-whopping nine of them further down on this page.

As always, instructions are included for several block sizes.

This time including 5", 7-1/2", 10" and 15".

Let's get started with this two fabric block!

General Instructions

The sample in this tutorial is a 10" finished block.

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

When you're 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 toward the darker fabric unless otherwise noted.

I use several common abbreviations on this page:

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

Step 1: Cut the Churn Dasher patches

Patches #3 and #4 are marked with 2 asterisks (**). These squares are used to make our half square triangles (HST) eight at a time.

Some quilters prefer to make their HST larger than required and then trim them down to size. I'm one of those quilters. So when I make this block, I add an extra 1/2" to each dimension of my #3 and #4 patches. Instead of cutting them 5-3/4"x5-3/4" for my 10" finished block, I'll cut them at 6-1/4"x6-1/4".

If your 1/4" seam is always spot on, use the measurements in the chart. If you want a bit of extra insurance add a bit.

There's a handy chart for you to download with all the numbers on it for this 8-at-a-time technique. Click here to download it.

Step 2: Assemble the units for your Churn Dasher

Two Patch Units

With RST, stitch one #2 square to a small background #1. Press with the SA towards the dark fabric.

Repeat for a total of 4 pairs.

Stitch 4 sets of small patches together

Half Square Triangle Units (HST)

We'll use a method that makes 8 HSTs at one time. You can find detailed instructions how to do this in our Beginner Quilt Block Patterns series under Half Square Triangles: Technique #4.

On the back of the large background square #3 draw a pair of perpendicular lines from corner to corner to form an 'X'.

With RST, layer the large dark #4 and background #3 squares and stitch a quarter inch away from both sides of both lines.

Sew on both sides of both lines

The arrow points to the anchor cloth. Start your stitching on one to
stop your sewing machine from 'eating' the point of your squares.

After the stitching is complete, the squares look like this.

After stitching for the HSTWe'll use the midpoint measurement to cut this in half through the center both vertically and horizontally.

Find the midpoint measurement or center of your #3/#4 squares. It is simply the size of the cut squares divided by 2.

Because I started with larger #3/#4 patches cut at 6-1/4" I had to do the math myself. The mid-point is 3-1/8" or 6-1/4" divided by 2.

If you cut your #3/#4 patches the exact dimension of 5-3/4", your mid-point is 2-7/8" or 5-3/4" divided by 2.

If you are making another block size, use the chart below to find the Midpoint measurement.

Block Size
#3/#4 squares
Trim HST to...
5" 3¾"sq 1⅞" 1½"
7½" 4¾"sq 2⅜" 2"
10" 5¾"sq 2⅞" 2½"
15" 7¾"sq 3⅞" 3½"

Cut your block in half at this midpoint both vertically and horizontally to create four squares. Then cut along the drawn diagonal lines.

You now have eight HSTs.


Check your HST against the 'Trim to...' size in the chart above. Trim as needed.

Again, for more detailed instructions on this technique go to Half Square Triangles: Technique #4.

With RST, align the edges of a HST with a BAC square. Stitch and press with SA towards the light fabric. (Photo 2, top) This is the only time in this block where you press towards the light—this is so the seams will nest and to reduce bulk.

Take a quick check from the front of the sewn unit to make sure the darker fabric isn't shadowing through to the front. If it is, trim the seam allowance of the dark so that it is shorter than the light one.

Repeat for the HST and #2 patch. This time press with SA towards the dark. (Photo 2, bottom)

Sew the to sub-units together, nesting the seam allowances and pinning if needed.

Press this seam towards the #2 square. (Photo 3)

Step 3: Assemble your Churn Dasher block

Lay out the pieced units.

Layout of the units and patches

Stitch into rows. Press with the SA as shown by the red arrows below.

Stitch patches into rows

Stitch the rows together.

Variations on a Churn Dasher design

No one was more surprised than me to see all the variations on this simple Churn Dasher quilt block drawing.

You will be, too!

And here they are...

Domino quilt block design


A two fabric version that looks completely different from the Churn Dasher quilt block, simply because of the color placement.

Farmer's Daughter

Three fabrics—a dark, a medium and a light—come together to create a star design.

Also known as: Two Crosses

Click here for instructions to make it.

Sister's Choice

Another three fabric block, with the addition of the dark squares on the sides it looks more like a bow, don't you think?

You may know it by one of its other common names: Churn Dasher quilt block, Five Patch Star,
Four & Star, 4X Star, Star and Cross

E-Z Quilt

In this variation, I'd choose to piece the brown fabrics as rectangles instead of 2 squares to simplify the piecing.

Rolling Star quilt block design

Rolling Star

The star theme continues with a reverse nine patch (the lighter patches are in the corners) in the center.

Souvenir quilt block design


Piece the center as one unit, and you've got the perfect place to display machine embroidery collections.

Star and Cross quilt block design

Star and Cross

Simplify the piecing by using a rectangle instead of 3 patches in the very center.

Father's Choice quilt block design

Father's Choice

The star almost disappears, with the turquoise creating almost a 'tulip' design.

Nine Patch Star

Nine Patch Star

It completely transforms with this two color placement.

All those variations from the simple Churn Dasher quilt block—who knew!
