Binding, Bias or Straight-cut?
 

When do you cut binding on the bias?

I always cut on the bias because more threads are exposed on the edge, which I think protects against fraying from wear. I think that if the binding is cut on the straight grain, then there's only 1 thread at the outside edge that can wear through quickly. Bias is also necessary when binding scallops or rounded corners.

mostly for curved projects, only because I'm lazy.

I have only used straight bindings except for the one i used purchased bias tape as a short cut. I have not done any with curved edges.

My experience is that I have used straight grain binding for over fifteen years and not had problems with fraying or excessive wear (and my quilts are mainly snuggle, lap quilts that get washed a bit). I have only used bias binding when I was binding a curved quilt and once when I had striped fabric that I wanted to "swirl" around the outside of the quilt and I achieved that through cutting it on the bias. But generally speaking, I personally don't bother to cut it on the bias otherwise. For me, it's simply not worth the extra time and effort. But as with all things quilty, do what works for YOU and makes you happy!! :)

I always do straight ones, but haven't done curved edges either.

I only cut on the bias if I'm binding a curve.

I have done both. I determine the cut based on the type of fabric. If I use a thick backing, then I prefer bringing the backing to the front and doing a hem around it rather than binding. I posted a tutorial over in the tutorial section on how to do this without excess bulk on the corners. The thick backing (like minkee or fleece) is much sturdier than cotton binding.

I do have one quilt with frayed binding that I need to cover up. It's been much loved so I'm not sure if it's because of the straight of grain or just lots of use over the years. The ones that I have hemmed show no stress on the edges.

The worst that I have done was buying that ribbon binding for a baby quilt. After a few washings it looks horrible.

Usually straight cut unless it is for a curved edge quilt. Also I like stripes for bindings and I always cut these on the bias just because I like the way it looks.

i use the straight cut. but if curves are involved, i use bias.
