How to Make Curved Quilt Corners: A Step-by-Step Tutorial

How to Make Curved Quilt Corners: A Step-by-Step Tutorial

Soft edges, simple steps, and a beginner-friendly finish

Forget the fuss of mitered quilt corners—let’s talk about curves.

Curved quilt corners are one of those little finishing details that can add a soft, polished touch to your quilt, especially on baby quilts, lap throws, or anything meant to feel extra cozy. Plus, they’re often simpler to bind than sharp angles. If you’ve never tried it before, this is your gentle nudge to give curves a go.

Tools You'll Need

These are my go-to tools for creating curved quilt corners:

  • Self-healing cutting mat

  • Rotary cutter

  • Fabric marker or chalk

  • Quilting ruler (optional)

  • OmniArc ruler by Omnigrid or a 12" dinner plate (or any similarly sized round object)

🪡 Step 1: Align Your Curved Ruler or Round Object

Place your quilted project on your cutting mat. If you’re using the OmniArc ruler, line up the 6" markings along both straight edges of one quilt corner. The center diagonal line on the ruler should sit right in the corner.

If you’re using a plate or other round object, center the curved edge so it reaches just about 6" in from both sides.

 

✏️ Step 2: Mark the Curve

Trace the arc of the ruler (or edge of your plate) with a fabric-safe marker or chalk. Your line should create a smooth, even curve from one side to the other. Repeat for all four corners.

✂️ Step 3: Trim the Curves

Carefully cut along the drawn line with your rotary cutter. Optionally, you can use a separate quilting ruler to help guide your rotary cutter along the curve if that feels helpful. Normally I would hold the ruler, but I couldn't take the picture and hold it. ;)

🧷 Step 4: Use Bias Binding for a Smooth Finish

Add your binding! Bias binding is ideal for curved corners because of its flexibility. It molds around curves without puckering or pulling. If you’ve never made or used bias binding before, I have a full tutorial that walks you through the process step-by-step. You can also buy bias binding. Non-bias binding may work too, I just haven't tried it.

I like to machine stitch the binding to the back of the quilt first then attach it to the front either by machine or hand (blind stitch or big stitch). I attached the binding in the picture below by machine to the back and front of my quilt. 

For attaching by machine or blind stitch, I use Aurifil 50 weight thread. But for big stitch binding I will generally use Aurifil 12 weight, 8 weight, or Floss. 

Congrats! You're finished.

Subtle, clean, and inviting

If you’ve ever felt unsure about how to finish a quilt with mitered corners, curved ones just might be your new favorite option. They’re simple to mark, quick to cut, and easy to bind—plus, they bring that soft, handcrafted feel I love so much.

Happy Quilting!
