I will copy the template and then put laminate over it, which adds some substance and stability but still keeps it easy to cut. I will put a piece of two-sided tape on the back of the template if rotary cutting (the stickiness of the tape doesn't last very long). You will soon get used to how much of the template must be visible underneath the ruler. My alternate method is to copy the template onto freezer paper, and then iron onto the fabric so it stays in place.
