Bias cut binding as compared to straight cut binding - for straight edges
Which do you prefer and why?
I use bias cut - because I think it wears better. I have two quilts on my couches that the outer layer of the binding is in shreds but the inside layer is still "good".
I can also get it to lay very smoothly with the little bit of stretch it has.
As to whether bias binding uses more fabric - if I have it, I will use it because I do like the way bias cut looks and handles.
