I think the most important thing is the first selvege to selvege fold in the fabric. It must be straight. Hold the fabric in the middle and let it fall. Keep adjusting until the selveges match exactly. Do not look at the ends. They may be WAY off depending on how the fabric was rolled on the bolt.
After I was able to fold accurately, my cuts improved tremendously by starching the fabric heavily before I cut it. I have also added clear grip stickers on the back of my ruler.
