There is not an easier way to do a long cut than the methods described by these ladies. BE SURE to listen to them about the test rip if you choose this method, especially on darker fabrics, as some of them tend to have a light colored or even white "glow" along the ripped edge, which may extend beyond your seam allowance. I'm sorry I am not explaining it very well, but if you ever see it, you'll know what I am talking about. Good luck!
