Usually I cut it WOF, but when the quilt calls for it, I do Bias.
Bias is such a pain to do.

I almost always cut straight across the WOF.

I'm glad you raised the question. Most of the time I cut WOF out of habit, unless I want a stripe cut on the bias. Will the corners be easier to miter if I cut lengthwise instead of widthwise?

I have always done 2 1/4" WOF..until this morning when I made a bias binding for a quilt with inside corners. So, after I put that on perhaps I'll be a convert.

I usually cut across as this gives me just a little give if I need it. If I'm using it on a curved piece, I would definitely go bias. Made some oval placemats and had to use bias for them. Watched Missouri Star's video on making bias binding, the cutting of it and though it was a little confusing to me, it worked out just fine.

I only use a bias on something that is rounded. I also like a three inch cut for my binding on a quilt. I like a beefy binding. Most of the time on the width on the fabric, but there is occasion I prefer the length of grain if the quilting is such as to demand a stable binding.
I used to only use the bias, but, I honestly think working with the straight of grain is a nicer finish and more stable.
I do not press any but the bias made binding. Then I use the clover binding making tools. I have them in every size they make and have used them many times for this or that not just quilts. I have even used them in my home deco and clothing construction.

I usually cut WOF strips, but this method looks very interesting!

I always use a book by Fons & Porter called Quilter's Complete Guide. I make a tube and it is called a continuous bias strips. It seems to be faster to me when I do it this way.
