Filled binding - Binding width
 

I would usually do a test run - maybe only six inches or so - to see if my binding width and seam allowance width would allow the binding to wrap around enough for hand sewing or machine sewing the second stitching.

I think there might need to be a bit of width difference if one is using binding cut on the bias or straight of grain.

I used to use the leftmost setting on my pfaff 1471 ( granddaughter has it now) to determine my binding width. If hand-sewn and cut on the bias, the strips were 2-7/8 inches wide. I was using warm n natural batting.

I also prefer a somewhat wider binding.

And i stopped sewing about half an inch from the edge so the miter would fold properly.

Very nice. I guess we all have our ways that work best. I like 2 1/4 inch mostly. I use a Brother PQ1500 and can get a nice straight binding and good mitered corners. That's the beauty of quilting - a lot of right ways to do things to get the results we want.

I also like to use a wide binding on my quilts. I might go smaller if it is a wall hanging or something that requires a visually smaller binding. I also adjust my needle so that the binding on the back ends right where the seam is to fill the binding and look good.
I used to use a bias binding all the time but I only use the bias binding now when there is a curve that must be accounted for. It is funny how you change over the years on your process of making a quilt. As they say, "Live and learn". I mean to say what works best for you sometimes changes as you see better results another way. Not everyone handles a part of quilting like another person does. Right?

Definitely more than one way to do a lot of things.

There are some things that are absolute musts for me in the process - that others have absolutely no use for.

So we will each do things our way until we are convinced another method is better. Learn and live.

A wider binding can look nice when there's an unpieced border at the outer edge. Rarely is that the case for me, so I cut my bindings at 2-1/8 to 2-1/4 so that I do not lose any points when I sew the binding on. I sew on to the front by machine, and hand stitch to the back.
