How to Make the Snowball Quilt Block

Snowball quilt blocks are an excellent choice for quilting beginners because of their easy construction and simple piecing. They look great by themselves in a quilt but also work well in combination with others, in particular the 9-patch block.

The traditional way to make a snowball block was to sew it as a 9-patch, with half square triangles (HSTs) units in the four corners. But now, most quilters use a much easier technique called the ‘Quick Corner Method’. That’s what I’m going to share with you today.

In this tutorial, I have focused on putting four blocks together to create a little flower design. Perfect for a funky cushion cover or tote bag panel.

At the end of the tutorial, I talk about how you can combine it with other blocks for use in a larger quilt.


  • All seam allowances are ¼”
  • RST = Right Sides Together
  • Each finished block is 6” x 6″
  • Finished panel is 14″ x 14″


The fabrics used in this tutorial are from our Floral Passion Fat Quarters Bundle.

Block Colours:

  • Colour A (light beige vine) cut (4) 6½” squares
  • Colour B (pink linen) cut (4) 2½” squares
  • Colour C (lilac vine) cut (8) 2½” squares
  • Colour D (dark purple leaf) cut (4) 2½” squares

Border Colours

  • Colour D (dark purple leaf) cut (2) 12½” x 1½” strips
  • Colour D (dark purple leaf) cut (2) 14½” x 1½” strips

Step 1

Take all of your small squares and draw a diagonal line from one corner to the opposite corner on the wrong side of the fabric. I draw my lines with a water soluble pen, but if you haven’t got one don’t worry as you will not see the line in your finished block.

Step 2

Take 1 large square and four small squares. Place your large square right side up and position your small squares so the you have RST. Place the colour A in the top left corner, colour B in the top right and bottom left corners and finally colour C in the bottom right corner. Pin in place and then sew on the diagonal lines that you have just drawn (as shown in the photo above).

Repeat for the other 3 blocks.

Finally add the two longer border strips to the top and bottom of your block. Trim off any excess. Press seams flat.

Quilts that Combine the Snowball Quilt Block and 9-Patch Block

You can combine the snowball quilt block with complementary blocks to make beautiful full quilt designs. In the 2 examples above, I’ve combined it with the simple 9-patch square block. If you’re new to quilting, you can learn how to make the 9-patch block in our squares quilt block tutorial.
