Fabrics for churn dash block


To make our finished 6 inch block you will need:

Light Fabric (yellow)

Two 2 7/8 x 2 7/8 inch squares

One 1.5 x 11 inch strip (will be sub-cut)

One 2.5 x 2.5 inch square

Dark Fabric (purple)

Two 2 7/8 x 2 7/8 inch squares

One 1.5 x 11 inch strip (will be sub-cut)

I have used fabrics designed by Fiona and printed by Prinfab on their cotton poplin fabric. Prinfab is a British fabric printing company which offers 18 different types of fabric for you to print your designs on.

Use a quarter inch seam allowance throughout.


Step 1

Create 4 half square triangle units as follows.

How to make half square triangles

Place two of the different 2 7/8 inch squares right sides facing and draw a faint line from corner to corner. Stitch a 1/4 inch each side of the line and then cut along the middle line to form a half square triangle unit. 


HST unit

Make another pair resulting in four complete units. Press the seams towards the darker fabric and trim off the little ears at the edges.


Step 2

Joining two long strips to make square units

Join the two long strips with right sides facing and then cut four 2.5 inch squares from the completed strip.


Step 3

Laying out a churn dash block

Arrange the component pieces of the block as shown above and stitch each row together pressing the seams towards the centre. Join the three strips together to form the block, nesting seams as you go for accuracy.
