Oh yes, forgot to mention about what I did the other day on one of the projects I was working on. I misread the instructions so I cut a good size piece of fabric incorrectly and had to recut another good size piece of fabric (27.5"). I didn't want to waste that piece of fabric though it was now a triangle shape so I looked thru the rest of the cutting instructions and decided instead of cutting strips WOF, I'd see what I could cut from the triangle shaped pieced. So I was still able to use most of the miscut fabric. So even if the instructions say WOF, sometimes you can make do with what you have on hand with little waste.
