How to Join Binding Strips

Let's talk about joining strips of fabric on the diagonal. This is useful when you are joining pieces of fabric for quilt binding. 

Joining fabric on the diagonal instead of perpendicular helps to create less bulk in your binding, making it smoother and easier to sew on. 

I will show two ways of joining fabric strips on the diagonal. They are about the same, it just depends on how your fabric is cut. 

The first way I will show involves fabric that has squared (ish) ends.

 First, flip the strip perpendicularly, right sides together.

 Next, draw a line diagonally, from where the fabrics meet and create little outside corners.

Sew on the line. Make sure you are starting and stopping right in the corners so that the fabric will line up correctly. 

Stitching on the line

 Trim 1/4 inch away from the sewing line. 

Trim the extra fabric off

 Open and press. (You can see I didn't start and stop exactly in the corners, so my strip doesn't exactly line up.)

 The second way to do this involves fabric cut on the diagonal at 45 degrees.

 First, flip the strip perpendicularly, right sides together so the edges match up.

 Line up the ends. There will need to be some hang over on both sides. What you are looking for is that the outside corners the hang over creates are 1/4 inch or more away from the edge. Draw a line from corner to corner.

 Stitch on the line. Trim off any excess over 1/4 inch. Open and press.
