Cutting Fabric for the Monkey Wrench Quilt Block
Accurate cutting is critical when making a monkey wrench quilt block.
Understanding Measurements
Many quilting mats show only quarter-inch markings, but this block requires 1/8-inch precision.
For example:
- 7/8″ is just before the next full inch
- Count carefully using your ruler markings
Cutting the Units
You will have four main units:
- A units
- B units
- C units
- D units
Label each piece using masking tape to stay organized while quilting your quilt block.

Step 1: Cutting and Preparing A Units
The A units are essential to your quilt block.
- Cut fabric strips to the required size
- Align corners carefully
- Cut diagonally from corner to corner
Important Quilting Tip
Always hold your ruler firmly when cutting. Slipping can ruin your fabric and affect your quilt block accuracy.
Repeat for both fabric colors.
Step 2: Cutting B Units for the Quilt Block
The B units are smaller and require extra care.
- Measure precisely (including 1/8″ marks)
- Align corners
- Cut diagonally
Because these pieces are small, quilting accuracy matters even more when making the monkey wrench quilt block.
Step 3: Preparing D Units
The D units are the simplest part of the quilt block.
- Cut squares to size
- No diagonal cutting required
These will form the center of your block during quilting assembly.
Step 4: Cutting and Shaping C Units
The C units add structure to your quilt block.
- Cut squares
- Cut diagonally once
- Stack and cut again using a 45ยฐ angle
Why This Matters in Quilting
Accurate triangle cuts ensure your quilt block aligns properly when sewn.

Step 5: Sewing the Center of the Monkey Wrench Quilt Block
Start assembling your quilt block with the D units.
- Place right sides together
- Sew using a quarter-inch seam
- Press seams open
Why Pressing Matters in Quilting
Pressing seams open reduces bulk, making your monkey wrench quilt block easier to quilt later.
Step 6: Adding B Units to the Monkey Wrench Quilt Block
Next, attach the B units.
Find the Center
- Fold triangles in half
- Mark the center
Align and Sew
- Match the center to the seam
- Sew with a quarter-inch seam
This step is crucial for maintaining symmetry in your quilt block.
Step 7: Attaching C Units
Now itโs time to build out your monkey wrench quilt block further.
- Mark centers on all pieces
- Align carefully
- Sew and press
Quilting Tip
Do not stretch fabric while pressing this can distort your quilt block.
Step 8: Finishing with A Units
The final step in completing your monkey wrench quilt block is adding the A units.
- Fold and mark centers
- Match seams precisely
- Sew and press
At this stage, your quilt block should fully come together.
Squaring Up Your Monkey Wrench Quilt Block
After assembling your monkey wrench quilt block, itโs important to square it up.
Target Size
- 6″ x 6″ finished block
How to Square
- Use a ruler
- Trim excess fabric
- Align edges carefully
Squaring ensures your quilting project stays accurate when joining blocks.
