Learning how to mitre corners on a quilt gives your finished quilt binding a professional look and is very easy to achieve. This is a very quick and easy tutorial to show you how.
We have a more detailed tutorial on making quilt bindings here. My double-fold binding was made 2.5 inches wide and pressed in half along the length to attach to the raw edge of the quilted quilt.
Make sure your quilt corners are square and the edges are straight.
Line up the binding raw edge to the quilt edge and stitch your binding with a 1/4″ seam. Stop 1/4″ before you reach the corner. Lock your stitch or reverse to secure.
Flip the remaining binding up to form a 45 degree triangle and finger press in place.
Bring the remaining binding down to meet the quilt edge. You can see the mitred fold in the picture above which should lie flat.
Pin the corner flat and then start stitching from the top of the quilt with a 1/4″ seam as before.
When you come to stitch your binding neatly onto the reverse, fold the binding to the reverse side and fold the corner to form a neat triangle as in the picture above (reverse side). The fabric will naturally want to form the mitre that you folded on the front..
This is the front of the quilt which shows the neatly mitred corner.
