Tutorial: How to Sew a Mitered Corner
Follow this step-by-step guide to create perfect mitered corners that will give your project a professional look! Choose quality 100% quilters’ cotton and pick up on darker hues within the top. Pull out a warp thread from the raw edge and cut along it with a non-slip straight ruler to create 17-inch squares.

Fold and press each side ½ inch towards the wrong side of fabric before unfolding again to trace creases with an erasable marker. Fold the corner into a point, ensuring the ends match the drawn lines before sewing together.

Backstitch at the beginning and end of the seam. Clip off the tip, leaving a scant 1/8 allowance, then re-fold the second fold inwards, making sure the creases line up. Push the pointy tips outward and press down the secondfold edges, stitching all four sides around using clover clips as needed.

Add binding techniques for a finishing touch, following tutorials from Sharon Schamber or Pat Sloan’s Jaybird Quilts blog post series on basics.


Gather the essential tools and fabrics for a beautiful mitered corner—you’re almost ready to begin! Start by selecting quality 100% quilter’s cotton, handkerchief linen, cotton sewing thread bundle, eraser fabric marker, and tweezers.

To complete the project, you’ll need a rotary cutter with 6 1/2 x 24 1/2-inch non-slip straight ruler, a self-healing cutting mat, and napkins. Make sure the binding picks up on darker hues within your quilt top for an attractive result! Sewing techniques such as mitered corners add strength and durability while giving it a frame-like finish.

Cutting with precision is key—align outer edges before stitching along the crease, then cut off the excess after turning it right side out using a point turner to push it out perfectly squared at 15×15 inches dimensions, if desired.

Binding serves not only aesthetically but also practically, protecting all your hard work from being ruined or worn down over time.


Begin by prewashing, drying, and ironing the fabric before creating mitered corners. Use a rotary cutter and self-healing cutting mat to cut out seventeen-inch squares. Fold each raw side inwards 1/2 inch towards the wrong side of fabric for hem allowance, then fold them back against itself at an angle to create a point.

Trace this crease with an erasable marker or disappearing ink pen for precision stitching later. Pin down both sides of folded corner together so they line up perfectly, then stitch along the marked line, backstitching when starting and finishing the seam.

Leave a scant 1/8th inch allowance after snipping off the tip of the corner. Carefully turn right sides out using tweezers or a point turner tool, making sure the points stay sharp before pressing flat with an iron.

Edge stitch around the free inner fold, pivoting at the mitered corner as you go. It’s important to choose a binding that’s strong yet durable enough, while also picking up darker hues within the quilt top design.

Binding serves as a final punctuation, adding character and framing your masterpiece.
