Tips for Success

• Fabric choice matters: Choose fabrics with strong contrast to make the design pop. This pattern is great for using fat quarters, jelly roll strips, or pre-cut fabrics.
• Seam allowance: Maintain a consistent 1/4″ seam allowance throughout to ensure accurate piecing.
• Pressing: Press seams toward the darker fabric or open them up if that works better for reducing bulk.
• Chain piecing: If making multiple blocks, try chain piecing (sewing continuously without cutting thread) to save time.

Variations

• Scrappy Version: Use different fabrics for each piece to create a fun, scrappy look.
• Color Placement: Experiment with color placement to change the look of the block. Try using a lighter fabric in the center square for a more open, airy design.
• Block Size: Resize the block to make smaller or larger quilt projects. Adjust the size of your fabric pieces accordingly.

Creating a Double Monkey Wrench quilt block is a rewarding experience, blending simplicity with eye-catching design.

Materials Needed

Before we begin, gather the following materials:

• Fabric: Two contrasting colors (light and dark) work best for this block. You can also use it like I did (light, medium, and dark). You can use solid or patterned fabrics depending on your style.
• Cutting tools: Rotary cutter and self-healing mat, or fabric scissors if you prefer.
• Ruler: A quilting ruler for precise cutting.
• Thread: Match your thread to your fabric or opt for a neutral color like white or grey.
• Sewing machine: Set with a quarter-inch seam allowance.
• Iron and ironing board: For pressing seams.

Block Measurements

Here are the unit fabric cutting measurements for a 4 ½”, 6”, 7 ½”, 9”, 10 ½”, and 12” monkey wrench quilt block pattern.

Block Layout

This block is laid out on a 3 x 3 grid, also known as a 9 patch block. Three rows and three columns. The easiest sizes to make are evenly divisible by three: 6, 9, 12 inch squares. However, I do have the measurements for the other sizes to help you.

Pattern Notes

The instructions below will produce a 12” quilt block.

Sew fabrics together using ¼” seam allowances.

Sew fabric with the right sides together.

Step-by-Step Instructions

Cutting the Fabric:

Start by cutting the following pieces.

• B = (1) 4 1/2″ x 4 1/2″ square from your dark fabric (for the center)
• A and D = (2) 5 1/4″ x 5 1/4″ squares from both the light and dark fabrics (for Half Square Triangles, HSTs)C = (4) 2 1/2″ x 4 1/2″ rectangles from your light fabric (for the outer bars)
• E = (4) 2 1/2″ x 2 1/2″ squares from your dark fabric or medium fabric (for the corners)

Make sure your cuts are as precise as possible to ensure your block comes together cleanly.

Making the Half-Square Triangles (HSTs) for the Corner Units:

Take the 5″ squares from both the light and dark fabrics. Place them right sides together and draw a diagonal line from one corner to the other on the back of the lighter fabric.

Sew a quarter-inch seam on both sides of the drawn line.Cut along the drawn line to create two HST units.

Press the seams toward the darker fabric and trim the HSTs to 4 1/2″ x 4 1/2″.

Repeat this process with the other two squares. You should have a total of (4) half square triangles.

Sewing the Two-Tone Blocks: Sometimes Called Bar Units:

Take one 2 ½” X 4 ½” light rectangle and one 2 ½” X 4 ½” medium fabric rectangle and sew together lengthwise using ¼” seam allowance. Press seams to the darker fabric.

Repeat this process three more times.

You should have a total of (4) two-tone units.

Alternative method of making the two-tone units using strip sets.

Cutting the Fabric using the Strip method for the two-tone blocks.

• Cut (1) 2 ½” X 18” strip of light fabric.
• Cut (1) 2 ½” X 18” strip of dark or medium fabric.

With the right sides together, sew the strips lengthwise using ¼” seam allowance. Press the seam to the darker fabric.

Sub cut the strip into (4) 4 ½” segments.

Assembling the Block

Refer to diagram for visual assistance.

• Lay out your pieces as follows:P
• lace the dark 4 1/2″ square in the center.Position a HST on each corner with the darker fabric on the inside.
• Place the 2 1/2″ x 4 1/2″ two-tone squares on each side of the center square with the darker fabric on the inside.

With the right sides together, sew the blocks together in rows.

Press each row as you go to ensure neat seams. The top and bottom row press seams out. Center row, press seams in.

Building the Final Double Monkey Wrench Quilt Block:

Once you’ve sewn each row, join the rows together to form the final block. With the right sides together, pin and nest the seams to ensure everything lines up neatly.

Sew the rows using a quarter-inch seam allowance. Press the seams flat for a crisp, professional finish.
