The flange always looks good but I do agree with quilting it. I did one that way and was constantly looking to see where I was to try to avoid flipping the edges back on itself. It was a pain, but does look nice. I quilted it myself on my longarm.

I agree...............

I have done flanges and it is a great way to add a little interest between the main body and the border. Adds a little dimension that I love.

A flanged binding is on the outer edge of the quilt and this person wants something between the body and the border. I too like a flanged binding but I also love the flange around the main body of the quilt.

A flange is easier too.

It really does come down to how it will be quilted. If it is being longarmed (especially with a panto), the flange will be a huge headache. If you're quilting it on a domestic machine it will be less of a problem, because you will be able to easily keep track of it. It can still get flipped around if you FMQ over it, though, so when you plan your quilting try not to cross it.

If it's going to be longarmed, I would suggest a very narrow border instead.

When I do very narrow borders I cut them maybe 1/2" wider than I want them and trim them to the width I want after it is sewn on. Even with starching I end up with distorted edges, so trimming after gives me a straighter edge.

I love putting a flange on mine, it really sets it off.

my cousin is a long armer and I asked her about it once. She said she just holds that area back.

I've found that a flange can really add something special to a quilt border. Go for it.
