Here's what you need...
1. Some piping (equal to the perimeter of your quilt plus 4-6"). This is harder to find than you might think. I used to buy micropiping at Joann's for when I make pretty smocked dresses, but was not able to find it. I ordered this from here. It is a perfect size. At 25 cents per yard, how can you go wrong. I have also heard you can use a thicker pearle cotton, though I have not tested this.
So, the last step is pretty much life as usual in terms of sewing on a binding. The only catch is that you have to be slow and careful, and plan to have to have areas that you go back and adjust to make the piping look pretty. Start midway along one side of your quilt. I set my seam to a little wider than 1/4" so that it covers the piping seam. On my machine, 1/4" is a setting of 5.3 and for the binding I used 4.7. It might be at most 1/16" inboard of the seam. It is enough that the threadline on the piping is concealed, and nothing but the tight little bump of the piping is visible. I do not pin my binding because there is enough bulk. I just stitch slowly and carefully. When you reach the corner, do as you usually do to get around the corner when applying continuous binding.... You are now all the way around your quilt, and the binding is sewn down to the top completely. Now take a careful look and see if there are any places that you need to go back and stitch closer to the piping or adjust. I won't lie, I spent nearly 3 hours putting the binding on (not the hand stitching!) this 75" square quilt. It will take some time.
Now, the quilt only needs a sleeve (ahh...150" more hand stitching!) and it is good to go!
