Posted by Elaine Huff on

Today let's sew together the Triangles quilt block. This traditional Triangles quilt block only uses Flying Geese and Half Square Triangles to make a delightful pattern. It's not too difficult - a confident beginner will be able to sew it together with beautiful results! Let's get started!

Fabric Requirements for a 12" Finished Triangles Quilt Block:

  • Light/Ivory: 1 - 4.5" square, 12 - 2.5" x 4.5" rectangles, 2 - 3" squares, and 4 - 2.5" squares
  • Medium/Coral Print: 2 - 3" squares, and 8 - 2.5" x 4.5" rectangles
  • Dark/Coral: 8 - 2.5" squares

Sewing Directions:

Half Square Triangle Units:

Step 1:

First thing is to make four Half Square Triangle units as shown below using the Medium/Coral Print 3" squares and the Light/Ivory 3" squares. Trim/square up the units to 2.5". You can find my method for making a Half Square Triangle block at https://fabric406.com/blogs/fabric406-blog/how-to-sew-a-basic-half-square-triangle-block

Flying Geese Units:

Step 2:

Using four of the Light/Ivory 2.5" x 4.5" rectangles and the eight Medium/Coral Print 2.5" squares, sew together four Flying Geese units as shown below. You will find my tutorial for making a basic Flying Geese block at https://fabric406.com/blogs/fabric406-blog/how-to-sew-a-basic-flying-geese-block

Step 3:

Now you can sew together four more Flying Geese units using the Dark/Coral 2.5" squares in place of the Medium/Coral Print 2.5" squares from Step 2.

Step 4:

Pair up a Step 2 unit and a Step 3 unit as shown in the picture below.

Step 5:

Sew the two units together and press the seam allowance toward the unit with the Medium/Coral Print fabric as shown below.

Corner Units:

Step 6:

Now you can pair up one of the Half Square Triangle units with a Light/Ivory 2.5" square and sew together as shown in the picture below. Press the seam allowance toward the Medium/Coral Print fabric. Repeat for a total of four units.

Step 7:

Take one of the Step 6 units and pair it up with a Light/Ivory 2.5" x 4.5" rectangles. Sew the two patches together and press the seam allowance toward the Step 6 unit as shown below. Repeat for a total of four units.

Putting It All Together:

Step 8:

From here the Triangles block goes together like a typical Nine Patch block. Lay out the Light/Ivory 4.5" square, the Flying Geese units, and the Corner units as shown below.

Step 9:

Sew the units together into three rows as shown in the picture below.

Step 12:

Well, except for the pressing. Press seam allowances away from the center of the block as shown in the picture below.

Conclusion:

The Triangles quilt pattern was fun to sew together. If I had pressed the seam allowances in the Half Square Triangle units toward the Light/Ivory fabric, I think it would be less bulky at the seam intersections. The original pattern only used a light and a dark fabric but I had to make it my own by adding in another color. I love the look of it and I think a nice secondary design emerges when multiple blocks are sewn together. Give it a try!

Layout Options:

Just a couple of layout options for this block so you can get a feel for what it would look like in a quilt.

Here is just a simple 4 x 4 layout with two borders.

In this one, I've just added sashing in between the blocks.
