2 1/2" binding, how wide do I sew it? 1/4"? 3/8"? ??
 

So, how wide do I sew it to the back when I want to machine sew it to the front? Thank you, Jeanne

I always use my 1/4" foot for the first seam. It gives me a nice straight edge and I don't cut off my points!

2-1/2 inch strips should be sewn with a 3/8 inch seam.

I sew 1/4 inch whether my binding is 2 1/2 or 2 1/4.

i use a 3 inch double fold sewn with1/4 inch seam hand stitch to the back---never go back to the smaller as this flips over soo much more easily

I always use a 1/4" seam when sewing on binding as I do when piecing.

I sew about a 3/8 inch seam, which is the width of my normal foot. It seems to work well for me.

As you can see, lots of ways to do it. I move the binding so that its edge is 1/4" from the edge of the quilt sandwich, then sew with scant 1/4" seam, then sew the back by hand. I wind up with a 1/2" binding. I move the binding closer to the edge if the quilt sandwich is thicker than usual.

i cut my binding strips at 2.25" and sew a .25" seam

I mostly use 2 1/2 inch binding and use 1/4 seam. then I flip it to the back and pin from the front right next to the binding, making sure to catch the binding on the back. then machine stitch. good luck.
if i hand stitch it on the back, i sometimes cut 2 1/4 inch binding. still stitch 1/4 seam though.
