In this tutorial I am using a 25 mm bias binding tool to makes approx. 4.8 meters of 1 inch bias binding.
Make you pattern piece by following the measurements in the diagram below.
Place your pattern onto your fabric making sure that you line up the grain line on your pattern with the selvedge of your fabric. Cut one piece.
Pin the two shortest ends together matching notches. Sew with a quarter inch hem. Iron the hem flat.
You will now see that you have a loop of fabric, with a 2 inch overhang on each side of your hem.
With a water erasable pen mark a series of points two inches from the edge of your fabric to use as your cutting guideline. You can mark them as solid lines if you prefer. Then cut along your guidelines.
You should now have a continuous strip of fabric that is 2 inches wide and approx. 4.8 meters long.
On the ironing board push one end of your fabric through your 25 mm bias binding tool (use a pin to help it through the tool at the start). I then pin the fabric to one end of my ironing board so that it frees up one hand then pull back the tool and iron the bias binding flat as it comes out of your tool.
Continue to do this for the whole length and you will now have a lovely long length of 1 inch bias binding in the fabric of your choice ready for your sewing project.
