How to Sew a Crab Claws Traditionally Pieced Quilt Block (or should we call it Wrench?)

    Looking for a bold and dynamic quilt block that’s easy to piece? The Crab Claws block is a perfect choice! This striking 12″ block is made with just squares and flying geese units, making it a quick and satisfying sew. With its sharp angles and strong lines, it resembles both the pincers of a crab and the sturdy shape of wrenches – making it a fantastic design for ocean lovers or the perfect quilt gift for a mechanic or handy person. Whether you’re adding it to a sampler or sewing up an entire quilt, this traditionally pieced block comes together with ease. Let’s get started!

    Fabric Requirements for a 12″ Finished Crab Claws Quilt Block:

    • Light/White: 1 – 4.5″ square, and 20 – 2.5″ squares
    • Medium/Floral: 4 – 2.5″ x 4.5″ rectangles, and 6 – 2.5″ squares
    • Dark/Aqua: 4 – 2.5″ x 4.5″ rectangles, and 6 – 2.5″ squares

    Sewing Directions:

    Two-Patch Units:

    Step 1:

    Make four Two-Patch units using four Light/White 2.5″ squares and four Medium/Floral 2.5″ squares like the ones shown in the picture below. Press the seam allowance toward the Light/White fabric. (I pressed mine toward the medium fabric and then when piecing the last steps realized that seams would nest easier if these units were pressed toward the Light/White fabric.)

    Step 2:

    Repeat Step 1 only using the Dark/Aqua 2.5″ squares in place of the Medium/Floral squares.

    Flying Geese Units:

    We’re going to be making four different colorings of a Flying Geese block. For a detailed tutorial of my no-trim method for making perfect Flying Geese blocks check out https://quiltembroiderypdf.com/how-to-sew-a-basic-flying-geese-block
     

    Step 3:

    Putting It All Together:

    Step 13:

    Lay out the Light/White 4.5″ square, the Corner units, and the Middle units as shown in the picture below. From here the block goes together like a basic Nine Patch block.
     

    Step 14:

    Sew the units into three rows as shown below.
     

    Step 15:

    Press the seam allowances away from the Middle units as shown.
     

    Step 16:

    Then sew the three rows together to complete the block.
     

    Step 17:

    And finally press the seam allowances toward the center of the block as shown by the picture below.
     

    Layout Ideas:

    This is your basic 4 x 4 layout.

    So I had to see what it might look like as a scrappy quilt! I would keep each block to three fabrics (light, medium, and dark) so I wouldn’t get confused with where each color goes when sewing the units.

    This is an example using a simple chain block as an alternating block.

    Here’s an on-point layout with dark sashing and cornerstones and background fabric used for the setting triangles.

    And lastly I have another on-point example with a simple chain block alternating with the Crab Claws block and also extending into the setting triangles.
