I use a 2.25" strip from the bias and curved corners. I hate mitering. But even if I have to miter, I still use bias binding. I find it a lot easier to miter the corners with it (but again, I avoid that if I can).
Last time I used my sister's method of sewing it to the front, folding it to the back and pin it in the ditch on the front, then stitch in the ditch. It worked out really well. I prefer to avoid hand sewing (it would take me forever because I have carpal tunnel syndrome and can only hand sew about 6" or less before I have to stop for a while).
