I cut mine at 2.5 inches. I find the 2.25 is just a little narrow for me. If I am doing a flannel quilt, I'll cut my binding at 3 inches as the thicker fabric just seems to need more binding. I have a friend who cuts her binding at 2 inches which I just can't handle. It all depends on the quilter and the quilt. I always cut continuous bias binding and I don't press it in half before attaching. Just folding it and applying it works well for me so that's what I do. I just use my longest Olipfa ruler (36") to draw the lines for my bias which works just fine for me. The only bias binding tutorial that I use is the one by Shelley Rodgers (you can google it) because it is so easy to follow (almost idiot proof) and again I can handle it!
