I use 2.5" as well.

At least 2 1/2" for me.

it depends on the width of the seam.

I prefer doing it as pull the backing around to the front, fold double and stitch, but if I do a separate binding I like it a little wider than my last one turned out using the double fold cut 2-1/2" and 1/4" seam, so next time I think I will cut it at least 2-3/4" or maybe even 3".

2 1/4" for me

2 1/4" for me as I prefer a tight narrow binding.

I use 2", but I never realized that most people use a larger width than that! I like a narrow binding. I machine stitch it to the front and hand stitch it on the back. I've never done a binding completely by machine, so I don't know if I would use a wider width then.

jcrow....your idea sounds great but I'm not quite sure on how to do it. Is there any chance that you could provide us with a tutorial? I think that would benefit a lot of us new quilters. Thanks in advance

I may be in the minority but I used 2.75 for my last quilt. I found it much easier to work with since I did it all on my machine.

I usually do 2 1/2 but decided to try 2 1/4 on a baby quilt I finished today. I like the way it turned out. I sew to the back and turn, machine sew on the front.
