I also machine baste before binding. It stablilizes the outside edge.

I pin the binding on the edge of my quilt BEFORE I trim away the extra backing and batting. It lays flat that way. I leave about 1/8 inch of the backing and batting wider than the seam allowance. MY binding is nice and full that way. I lost points at a quilt show because my binding was not full.

I usually quilt all the way to the edge and I don't cut off the excess backing or batting until after I attach the binding (as long as the quilt is basically square, that is!).

When I cut away the excess, I use pinking shears and leave about 1/4" from the seam. I find that I fill the binding out better that way.

Is that hand or machine sewing all the way around?

I always baste the edges as I quilt on my longarm machine. Many, many of the my customers have thanked me for doing this. They say it makes sewing on the binding much easier for them.

If I am using a polyester batting I will sew around the outside. If I use cotton, such as warm and natural, it seems to "stick" better. I tried not sewing once with polyester and the fabric folded over.

I quilt to the edges so I don't baste. I do pind the edges before quilting though

I zig zag the edges then add the binding.

I don't do it...wasn't taught to do it, and never found it necessary.

I baste every quilt edge. If I'm at the machine I'll machine baste and if I'm watching a tv show I'll hand baste. Both ways work equally well for me, but I defintely do baste because of the ease with adding the binding. I baste with less than 1/4 so that I don't have any of the basting stitches show and I don't need to pull them out.
