Triangle Weave quilt block tutorial

Skill Level: Beginner

Grid: 4x4 (four patch)

The Triangle Weave quilt block is all about pointy points. To achieve them, my preferred method includes paper piecing. However, not everyone is wild about that technique!

To accommodate both preferences, on this page you'll find instructions for paper and traditional piecing methods in four different sizes. The choice is yours to make.

Let's get started!






Construction Instructions

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

Grid size: 1-1/2"

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

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.

Whether I'm paper piecing or using rotary cut patches, this is the best 'trick' I've found for getting the flattest quilt blocks. Click the 'blue ribbon' to the right to learn how you can do it, too!


Step 1: Download paper piecing patterns/templates

If you are using only traditional piecing techniques, you can skip this step, otherwise...

You'll need Adobe Reader (the latest version is recommended) installed on your computer in order to open and print the paperpieced units (a new window will open so you can download it without leaving this page).

Click here for our free downloadable pattern for the 3" finished Birds in the Air (BitA) unit. You'll need one copy

To print, open the downloaded file, and select the "Print" option.

To print blocks at the correct size, under 'Page Sizing and Handling' in the Adobe print menu, set 'Custom Scale' to 100%. Click here to see what it looks like on the Print Menu page.

Step 2: Cutting

In both charts below:

  • The dimensions listed are for squares. For example, in the blue chart, for our 6" block, Patch 1 is cut from a dark 2-3/8" x 2-3/8" square that is sub cut once on the diagonal.
  • Patches 6 & 7 are used to make the small half square triangles. You may wish to cut these patches a bit bigger and then trim the finished HSTs to size as is shown in the instructions. Again, the choice is yours!

Choose your favorite method of piecing and then choose the corresponding chart below. Our Fabric A is a dark and Fabric B is a light, but you can just as easily reverse them for a different look.

Step 3: Construct the subunits for our Triangle Weave

HSTs

Make 4

Draw a diagonal line on the back of the #8 light squares.

With RST, layer each marked patch with a #7 dark patch and sew 1/4" from the line on both sides.

Cut apart on the line.

Press.

If you started with over-sized patches, trim the finished patches to the dimension indicated on the chart above.

HST subunit

HST Subunits

Make 2

Sew a light 2" square to the dark side of a small HST you just constructed. Repeat 3 more times adding the square to the same side.

Press with SAs towards the solid square.

They look like this.


Prepping the patches for the HST Subunit


Arrange them into pairs with the dark triangles kitty corner from each other. The seams nest to assist in matching.


Arrange the patches for stitching


Stitch and press. Repeat for the second pair.

Closely Related Blocks

A handful of patchwork designs share the same basic structure as our Triangle Weave quilt block.

Goose and Goslings quilt block


In this first one, the Goose and Goslings quilt block, can you see the difference?

The HST subunits are rotated a 1/4 turn.

This block is know as a Bow Tie Variation, Crosses and Losses, Double X or Fox and Geese.



School Girl's Puzzle quilt block


In this variation, our Triangle Weave is flipped on its vertical axis and two additional fabrics are added to the mix.

It's other names are Hourglass and Old Maid's Puzzle. (The underlined links lead to other blocks by the same name.)
