2015 Adventure Quilt Block of the Month #10

Half-square triangles are a go-to traditional quilt block element. They are so easy to make, I had to include them in the 2015 Adventure Quilt. Once you see how fast these are to stitch, you may find that this month’s block of the month will turn into blocks of the month with many layout options. October’s Block of the Month in The 2015 Adventure Quilt is the Triangle Medley. To create the block, use the 5-in-1 Sliding Gauge. Here’s how:

Block #10: Triangle Medley

All blocks in The 2015 Adventure Quilt measure 12-1/2″ x 12-1/2″, creating a 12″x 12″ finished block. 1/4″ seam allowances are included.

Notions, Fabrics, and Supplies:

Get started by choosing fabrics. Any three color combinations will work. I had a surplus of black, white, and chartreuse green in my quilting fabric scraps. If you’ve been following along, you know that this Block of the Month series is a scrap fabric adventure.

Create Half-Square Triangles

We are creating 16 half-square triangle blocks. This means, we’ll need eight total pairs of squares.
-Four pair will be cut from white fabric with black fabric.
-Four pair will be cut from white fabric with green fabric.

  • Layer two strips, 3-7/8″ x 16″, matching right sides.

  • Rotary cut the two layers to 3-7/8″ x 3-7/8″ squares.
  • Cut four pair from this strip.
  • Layer white and black fabrics to cut four additional pairs of squares. (not pictured)
  • Use the 5-in-1 Sliding Gauge to check for accuracy.


  • Sew 1/4″ from each side of the marked diagonal line.

  • Chain stitch.
  • Cut the stitching apart.
Note from Nancy: Red stitching lines have been added digitally. When stitching, use coordinating threads.
  • Use rotary cutting tools to cut the half-square triangle blocks along the marked line.
  • Press the seam allowance towards the darker fabric.

Decide on a Block Arrangement

As with many four by four grid blocks, the arrangements can vary quite a bit. I’ll be the first to tell you there is no wrong or right way to arrange your 16 half-square triangles. The October block will have many possibilities. I have narrowed my triangle arrangement down to two choices. But, you’ll find twelve additional block ideas in my No Hassle Triangles Book.

  • Decide on a layout with triangles pointing in the direction most pleasing to you.
  • Use a 1/4″ seam allowance to sew pairs together to form rows.
Note from Nancy: The most important thing to remember when creating the block is to press the seam allowances in one direction, alternating by row, as shown below. This will guarantee the seams will lock with each other to create more accurate triangles.

  • Use a 1/4″ seam allowance to join the rows.

What would a Quilt Look Like?

As part of this Block of the Month series, we have included ideas of what a quilt might look like if you made it with only this month’s block.

  • The Great X quilt is a Triangle Medley block arranged in a traditional grid with no sashing strips. 48 blocks are featured.
  • This next design is based on a single block. The block is directional and, as we all have done, one set of blocks is made in the opposite direction. I’ll show you the planned block and the new block side by side. The accident worked out well to create a quilt design that appears to make a spinning star design when the blocks are alternated. Without sashing, this quilt features 35 blocks.
  • Using the blocks as planned, directional and all pointing the same direction, I created the quilt below by adding sashing to 35 quilt blocks.

    I also love the spinning star. Will all these blocks be available ibn print from at the end of the bom project?
