Conventional quilt binding is made from a strip of fabric folded down the middle along its length, sewn to the front of the quilt then flipped and sewn to the quilt backing. However, it is possible to use two colours in the quilt binding so that you have one colour showing on the front of the quilt and a different colour showing on the back of the quilt. This can add interest to your quilt and can also allow you more choice in your backing fabric.
Making the two colour quilt binding
Cut strips of the two colours that you wish to use. I used 1.1/4″ strips, but could easily have used 1″ strips. Join them together along the length using a 1/4″ seam.
To join two lengths of the two colour strips, place them at right angles as shown, right sides together. Note which way the colours are on the two separate strips. Stitch along the diagonal and trim the excess triangle about 1/4″ beyond the seam.
When opened out, this gives a straight line of two colour quilt binding. The diagonal seam makes it less bulky. Fold the binding in half along the seam so that you have one side white, one side black. Although you will need to open it out to sew it to the quilt, it is much easier to sew the second side of binding on if the seam has been pressed.
Sewing the two colour quilt binding to the quilt
With right sides together and leaving a few inches spare at the beginning place the binding on the edge of the quilt and stitch in place. Note that the black fabric only is being sewn to the quilt.
At the quilt corner, stop sewing 1/4″ before the edge of the quilt and remove the quilt from the sewing machine. Fold the binding up at right angles away from the quilt. Put your finger on the edge to hold this fold and bring the binding back down in line with the next edge to be sewn. Start sewing again from the edge and continue all the way round the quilt. Join the ends of the two colour quilt binding in the usual way.
Flip the binding over to the back of the quilt, turn under a small seam and slipstitch the second edge of the two colour quilt binding (the white in the photo) to the back of the quilt.
