Cheryl Brickey from Meadow Mist Designs and the Meadow Mist Designs shop shows you how to make this pretty half-square triangle (HST) block, featuring a gorgeous selection of Oakshott Cottons.

I am very excited to share with you a tutorial for an Oakshott Half Square Triangle Pillow. I love half square triangles (HST) and small piecing, and this was a great opportunity to combine both. I designed the pillow to look like a random arrangement of a whole bunch of small HST… 99 to be exact.

For one 18” pillow you will need:

  • Fat Eighth Bundle of 10-14 Oakshott Fabrics (or equivalent amount of fabrics). I used the 14 piece fat eighth Oakshott Impressions bundle available from Contemporary Cloth.
  • 22” x 22” Piece of Batting
  • 22” x 22” Muslin (or other backing fabric for the pillow front)
  • Removable Marking Device
  • Backing Materials (½ yard of fabric, optional zipper, and optional fabric for binding); the amount of fabric and other material requirements will depend on the pillow finishing method.
  • 18” Pillow Form (I used a 20” pillow form because I like my pillows overstuffed.)

Before we start, make sure that you have your scant ¼” seam allowance set. Because we are piecing so many small pieces together, a seam allowance that is even a little off can lead to piecing issues.
In the pillow there are 12 HST (3” finished), 27 HST (2” finished), 60 HST (1” finished), and 24 rectangles (1” x 2”) finished. These HST and rectangles are combined together to form 9 total blocks, each measuring 6½” x 6½” unfinished (6” x 6” finished).

Step 1: Cutting the Fabrics
From the fat eighth bundle cut a total of 12 squares (4” x 4”), 28 squares (3” x 3”), 60 squares (2” x 2”), and 24 rectangles (2½” x 1½”) from a variety of fabrics.

If you are using the same Oakshott Impressions 14 piece fat eighth bundle cut:

  • 1 square (4” x 4”) from 12 of the fabrics
  • 2 squares (3” x 3”) from each of the 14 fabrics
  • 4 squares (2” x 2”) from 10 of the fabrics and 5 squares (2” x 2”) from 4 of the fabrics
  • 2 rectangles (2½” x 1½”) from 10 of the fabrics and 1 rectangle (2½” x 1½”) from 4 of the fabrics

Note: The number of number of pieces cut from each fabric will depend on the number of different fabrics used.

Step 2: Making the HST
a. Place two matching sized squares with right sides together. Draw a diagonal line using a removable marking device on the back of one of the squares (shown as the solid line).

b. Sew 1/4” from the solid line (shown as the dotted lines). Cut on the solid line and press seam open or towards the darker fabric.

c. Trim the HST units to 3½” x 3½” (12 HST), 2½” x 2½” (28 HST), and 1½” x 1½” (60 HST).

Step 3: Forming the Blocks
To make the illustrations easier and clearer, the blocks are colored according to size (finished sizes).

For each of the blocks (A, B, C) arrange all of the pieces then, following the diagrams, sew the individual pieces into sub-blocks. Then sew the sub-blocks together to form the block pressing all seams open. Each block (A, B, C) should measure 6½” x 6½” unfinished (6” x 6” in the pillow).

Make 3 Block A:

Make 3 Block B:

Make 3 Block C:

Step 4: Sewing the Pillow Top
Arrange the blocks as shown below, sew blocks into rows, and sew rows into the pillow top. Press all seams open.

Step 5: Quilting the pillow top
1. Layer the quilt top, batting and muslin backing.

2. Baste and quilt as desired. For my quilt top, I quilted randomly spaced straight lines across the pillow top at the same angle as the diagonal of the HSTs.

Step 6: Finish the pillow
Finish the pillow with your favorite method. Some options include an envelope back, an invisible zipper or a covered zipper with or without a binding. More information about finishing pillows can be found here.

I used my favorite method, an invisible zipper, to complete my pillow using a backing of linen.

Congratulations! You now have a finished HST pillow. I would love to see your finished pillows; you can even post them in the Meadow Mist Designs group.

    Love the cushion, thinking of making a lap quilt with this pattern for our granddaughter.
    With the cushion did you just use plan fabric for the back ?

    Love this! I’m thinking a whole scrap quilt. It would be a good use for all those little triangles that are cut off sometimes! I’ve been sewing them together into HST and saving them for a rainy day. Thanks for this idea – it’s raining!
