How to prepare a 2.25" non bias binding.
First, figure out how much material you will need. To do this measure the perimeter of your quilt. So my quilt is 45"x60" so add 45+45+60+60=210. I will need a minimum of 210" of binding.
Now take 210/42 (the average width of your material.) = 5 cuts. So I will need 5 - 2.25" cuts.
Now take 2.25x5=11.25. So I will need 11.25 inches of binding. (I usually purchase a little bit more just to make sure I've got enough.)
Have I lost you yet?
Make sure that the edge of your material is square.
Open your strips, lay them on top of each other as shown in the image above.
Cut on the bias line towards the right. As shown in the image above.
Now, move to the opposite end and line the materials up on the bias line again.
Cut again going towards the right.
Your fabrics should line up as shown in the image above.
Lay the materials right sides together and stitch. Make sure to leave a 1/4" dog ear.
Repeat on all seams. You will want a long strip of binding material.
Press the seams open.
Walla, your binding is complete.
If you don't plan on using your binding right away. Here is a great way to store your binding.
Wrap the binding over itself around your ruler.
Slide the material off the ruler and it's all nicely together.
Simply pin a little note on it with the total number of inches of binding if you're not planning on using it for a while.
