Prepare supplies.

1. Per above, you will need will need:

• 1 Baby Bolt (A) : Quilt backing & diamond piece
• 3 Fat Quarters (B, C, D) : Diamond pieces
• 1 Solid Colour Cotton Bundle (E) : Diamond “background”

Take your time selecting coordinating fabrics. The colours you select should be complimentary to each other, but do not have to be an exact match.

Hint: Start with a printed fabric that incorporates many colours (A), and then choose fat quarter prints with colours from this palette (B, C, D). For the diamond background, choose a solid colour that is present in at least one of the other fabrics (E).

Cut fabric.

1. Cut the following number of squares measuring 6 7/8” (17.5 cm).
• 5 squares from A
• 5 squares from B
• 5 squares from C
• 5 squares from D
• 18 squares from E

2. Cut quilt back measuring 36 ½” x 36 ½” (93 x 93 cm) from A.

Create half square triangle quilt blocks.

1. Couple each E square with one each of A, B, C, & D squares, with right sides together.

2. Use blue marking pencil to trace a straight diagonal line from one corner of the square(s) to the other.

3. Pin square couples together along new centre diagonal line.

4. Sew ¼” (0.5 cm) on either side of the blue line. Repeat for all square couples.

Hint: Red thread used here for visibility. Use a neutral white or colour matching thread.

5. Cut along blue line, between both stitch lines.


Hint: The fastest way to stitch multiple blocks is by “chain stitching”. Once you have finished stitching on one side of the diagonal line, have the next one lined up for stitching right away. Then, go back and sew the other side.

6. Press along flat seams.

7. Open seams and press seam allowance toward the darker fabric.

Hint: “Press”, do not iron! Dragging the iron might cause the blocks to shift out of shape. Instead, gently press the iron over the blocks, focusing on the seam.

Assemble blocks for Diamond Picnic Quilt top.

1. Design your diamond blocks using four half square triangle blocks.

2. Lay out quilt blocks according to this design. The quilt will be three “diamond blocks” across and three “diamond blocks” down, for a total of nine diamond blocks.

3. Begin joining half square triangle blocks, two at a time, starting with your top row.

4. Match blocks with right sides together. Pin and sew at a ¼” (0.5 cm) seam allowance.

5. Continue to pin and sew, assembling quilt rows.

Hint: Press seams as you go.

6. Now, join rows to assemble quilt top. Be sure to match the blocks carefully so that they meet at the block seams.

Hint: To reduce bulk, press seams open when matching block diamond points and trim away excess fabric.

Hint: If your blocks don’t match up perfectly, don’t fret! Next week, we will explore creative ways to turn “matching mishaps” into design details.

Finish Diamond Picnic Quilt.

1. Lay finished quilt top on quilt back with right sides together.

2. Pin baste quilt beginning in the centre, and working your way toward the edges: this will keep the quilt in place when you join both layers.

3. Pin and sew along all four sides of the quilt, leaving a 6” (15 cm) gap.

4. Trim corners diagonally to reduce bulk, then turn quilt through gap. Press edges.

Hint: Get sharper corner points by gently pushing out turned corners with a finger presser, point turner, or gently using the tip of a marking pencil.

5. Hand sew gap closed.

6. Topstitch around all four edges of the quilt at ¼” (0.5 cm) seam allowance.

7. To keep layers together, topstitch in straight lines around each of the nine diamond blocks and/or stay tuned for next week’s project, where will we tackle “tacking”!

Hint: If you have one, use a walking foot for topstitching. This will prevent the presser foot from shifting layers apart.
